Studies on the Optimum Model of Forest for Soil and Water Conservation
12th ISCO Conference Beijing 2002 Studies on the Optimum Model of Forest for Soil and Water Conservation Li Shuren, Zhao Yong and Yan Zhiping School of Forestry, Henan Agricultural University Zhengzhou, 450002 E-mail: [email protected] Song Xuan The Institute of Applied Ecology, The Chinese Academy of Science,Shenyang, 110015 Abstract: This paper dealt with the soil and water conservation benefits on different kinds of vegetation along the Yangtze River valley in Xixia county, Henan Province. The four kinds of vegetation are dense trees with middle-dense shrub and loose grass(DMDL), loose trees with middle-dense shrub and dense grass(LMDD), dense shrub and middle-dense grass(DMD) and gradient farmland(GF). The results show that the annual surface runoff and soil erosion were 33.94 mm and 3.603 t hm-2 on DMDM; 2.885 mm and no soil erosion on LMDD; 21.035 mm and 0.384 t hm-2 on DMD; 36.110 mm and 32.657 t hm–2 on GF. The soil and water conservation benefits on the four types of vegetation were in the following order(from high to low): LMDD > DMD > DMDL > GF. And also the soil and water conservation benefits have the following order, grass > shrub > tree, based on the comprehensive analysis of the height between canopies and ground, and the force of rain dropping on the soil. LMDD was suggested to be the optimum structure model for obtaining the ideal soil and water conservation benefits and the best usage of different vegetation. Keyword: forest, soil and water conservation, optimum model, vegetation The effects of forest on soil and water was a important problem for sustainable development. -
Addition of Clopidogrel to Aspirin in 45 852 Patients with Acute Myocardial Infarction: Randomised Placebo-Controlled Trial

Study on Evaluation of Ecological Environment Quality and Temporal-Spatial Evolution of Danjiang River Basin (Henan Section)
Pol. J. Environ. Stud. Vol. 30, No. 3 (2021), 2353-2367 DOI: 10.15244/pjoes/128110 ONLINE PUBLICATION DATE: 2021-02-10 Original Research Study on Evaluation of Ecological Environment Quality and Temporal-Spatial Evolution of Danjiang River Basin (Henan Section) Shi-Dong Wang, Jin-Jin Si*, Yong Wang School of Surveying and Land Information Engineering, Henan Polytechnic University, Jiaozuo, Henan 454000, P.R. China Received: 28 April 2020 Accepted: 3 October 2020 Abstract The Danjiang River Basin (Henan Section) is the water source of the Middle Route of the South-to- North Water Transfer Project. Its ecological environment quality has received increasing attention. In this study, on the basis of the ecological environment of the study area, we constructed the evaluation index system from four aspects: ecological basis, ecological structure, ecological stress and ecological benefits. The variable fuzzy set model was improved by using the central point triangle whitening weight function and the relative difference function. The ecological environment quality of the Danjiang River Basin (Henan Section) in the past 20 years was evaluated, and the evolution patterns and causes of ecological environment quality were analyzed by combination with land use changing. And the results showed that the area with better ecological environment quality was significantly larger than the deterioration area. The area with poorer grade was decreased from 441.22 km2 in 1998 to 3.93 km2 in 2017, and its proportion was correspondingly decreased from 2.23% to 0.05%. The area with the ordinary grade was decreased from 4528.79 km2 in 1998 to 2636.47 km2 in 2017, and its proportion was correspondingly decreased from 53.67% to 31.24%; The moderately graded area was increased from 3132.7 km2 in 1998 to 5206.88 km2 in 2017, and its proportion was increased from 37.12% to 61.71%; the area with good grade was increased from 319.58 km2 in 1998 to 579.01 km2 in 2017, the area with the excellent grade of an evaluation rating was almost unchanged. -
New Dinosaur Egg Material from Yunxian, Hubei Province, China Resolves the Classification of Dendroolithid Eggs
New dinosaur egg material from Yunxian, Hubei Province, China resolves the classification of dendroolithid eggs SHUKANG ZHANG, TZU-RUEI YANG, ZHENGQI LI, and YONGGUO HU Zhang, S., Yang, T.-R., Li, Z., and Hu, Y. 2018. New dinosaur egg material from Yunxian, Hubei Province, China resolves the classification of dendroolithid eggs. Acta Palaeontologica Polonica 63 (4): 671–678. The oofamily Dendroolithidae is a distinct group of dinosaur eggs reported from China and Mongolia, which is character- ized by branched eggshell units and irregular pore canals. The ootaxonomic inferences, however, were rarely discussed until now. A colonial nesting site was recently uncovered from the Qinglongshan region, Yunxian, Hubei Province, China. More than 30 dendroolithid egg clutches outcrop on the Tumiaoling Hill, including an extremely gigantic clutch containing 77 eggs. All clutches were exposed in the Upper Cretaceous fluvial-deposited Gaogou For mation. In this study, we emend the diagnosis of the oogenus Placoolithus and assign all dendroolithid eggs from the Tumiaoling Hill to a newly emended oospecies Placoolithus tumiaolingensis that shows greatly variable eggshell microstructure. Moreover, our study also disentangles the previous vexing classification of dendroolithid eggs. We conclude that Dendroolithus tumiaolingensis, D. hongzhaiziensis, and Paradendroolithus qinglongshanensis, all of which were previously reported from Yunxian, should be assigned to the newly emended oospecies Placoolithus tumiaolingensis. Key words: Dendroolithidae, Placoolithus, colonial nesting, Cretaceous, China, Yunxian, Tumiaoling Hill.

Poverty and Social Dimensions Analysis, and Summary Resettlement Action Plan
38 Appendix 2, page 1 POVERTY AND SOCIAL DIMENSIONS ANALYSIS, AND SUMMARY RESETTLEMENT ACTION PLAN A. Introduction 1. The Project specifically targets poverty intervention by addressing critical agricultural and water supply constraints in a poor inland province. Because the water supply and irrigation component necessitates some resettlement from the pump site and regulating reservoir, a resettlement action plan was prepared. B. Socioeconomic Profile of Potential Beneficiaries 2. Demographic features. Agricultural communities in West Henan constitute about 83 percent of the total population, rising to 95 percent in Yichuan and Songxian. Twelve of the 32 counties in the project area are nationally designated poverty counties.1 While 98.4 percent of the population is ethnically Han, there are 18 different ethnic minority groups in the project area. Most counties have one or more ethnic minorities, on average 12 minority groups each. Almost 80 percent of the total minority population is accounted for by the three largest minorities: Muslim Hui, 61 percent of all minorities and 1 percent of total population, are concentrated in Zhengping, Dengfeng, Yuzhou, and Xinmi counties; Manchus, 11 percent of minorities, are concentrated in Nanzhao County; and Mongols, 7 percent of minorities, are concentrated in Neixiang County. The average household size is 4.20, slightly smaller than the province average of 4.59. Average household sizes in counties range from 3.3 in Luoyang to 5.0 in Yichuan. The average family size in Henan Province is 3.86, suggesting that, on average, most families have one additional household occupant (often a grandparent). 3.

Out of the most severe trial, their overflowing joy and their extreme poverty welled up in rich generosity.” 2 Corinthians 8:1-2 “What kind of church is the Chinese house church?” I was asked this question once by a Western Christian who had never been to China. As he continued, it became apparent what he really wanted to know was what kind of denomination the Chinese house churches are. Are they an evangelical church? Baptists? Charismatics? I thought about his question for a few minutes before answering, “The house churches in China are a Biblical kind of church.” That answer didn’t satisfy him, but it is the most honest answer I knew to give. Note I didn’t say “a perfect church” but rather “a Biblical church.” The Chinese Church has plenty of problems, temptations, trials and weaknesses. It contains those who have various theological views, those who fall into sin, and those who cause division, just like the New Testament church. But the Chinese house churches are also like the early Church in that the vast major- ity of believers are fully committed to Christ, willing to die for Him and willing to live every moment for His glory. -

Study on Carrying Capacity of Resources in Danjiangkou Reservoir Area Based on GIS Technologies
Study on Carrying Capacity of Resources in Danjiangkou Reservoir Area based on GIS Technologies Ke Liu, Yuhang Gan, Zhengyu Luo and Fanghong Ye Land Satellite Remote Sensing Application Center, Ministry of Natural Resources of P. R. China, Beijing, China Keywords: Carrying Capacity of Relative Resources, Sustainable Development, Mid-Route of the South-North Water Diversion Project, Danjiangkou Reservoir, GIS. Abstract: The environmental health and green development of the water source area of Mid-Route of the South-North Water Diversion Project (SNWDP) is not only essential for ensuring that “The clear water is sent to Beijing”, but also an important prerequisite for sustainable development of society and economy in the water source area. Based on national geographic survey data, basic surveying and mapping data and statistical yearbook data, this paper used the model of relative carrying capacity of resources to estimate and analyze the carrying capacity of relative natural resources (CCRNR), carrying capacity of relative economic resources (CCRER) and carrying capacity of relative resources (CCRR) and their spatial-temporal changes in the Danjiangkou Reservoir area of the water source area of the Mid-Route of SNWDP from 2009 to 2015 by Geographic Information System (GIS) technologies. The results were shown that: (1) CCRR increased significantly compared with that in 2009. However, CCRR in the study area was still overloaded in 2015. (2) CCRNR was rich, but decreased from 2009 to 2015. (3) CCRER was in a overloading state, which increased obviously from 2009 to 2015. The improvement of CCRER was the main reason for the sustainable growth of carrying capacity in the study area.
