Exploring the relationship between cultivated land change and economic development has become a hot issue for scholars.in this paper,The methods of regression analysis, land use elastic coefficient method, location entropy are used to empirically describe the relationship between cultivated land change and economic development.The results show: Since the 20th century, the change of cultivated land area has experienced three distinct stages of change, showing a process of recovery, decline, and steady evolution in Henan Province. The per capita cultivated land area is characterized by an upward trend, and the per capita cultivated land area is increasing year by year. In general, the intensive use of cultivated land in Henan Province is still not high, but the momentum of a sharp decline in cultivated land is basically controlled. The change of cultivated land area and economic development showed a four-time curve fitting relationship, which indicates that the path dependence of economic development on cultivated land occupation still exists, and cultivated land supports the rapid development of economy.The research results of the relationship between cultivated land change and economic development by using location entropy show that the spatial layout of the urban area is less than 0, and the regularity is not strong.The location where the location entropy is between 0-1 is mainly located in the central part of Henan Province;The cities with location entropy greater than 1 are mainly located in the eastern part of Henan. 1 The introduction cultivated land resources reducing is one of the major Cultivated land resource is human survival and cause of economic development, showing the trend of economic development of the basic factors of arable land decrease with economic production.But with the rapid development of development.Some scholars think that the cultivated urbanization and industrialization, the problem of land change and the economic development of a linear cultivated land loss caused extensive concern of the negative correlation between [4], some scholars of government and academic circle [1].Foreign scholars parts, according to a study by a rapid decline in of regional land use and interactive relationship of cultivated land with the increase of the per capita GDP, economic and social development have a profound characterized by exponential decline trend [5].Also the understanding of, and cobb Douglas production scholar thinks, between cultivated land and economic function model is adopted at quantitatively analyzes development showed a similar to the environmental the factors such as land, capital and labor contribution kuznets inverted "U" type curve characteristics, such to economic growth.Chinese scholars on the as Mr Fukuda of tianjin, shandong [6], gui-shan Yang relationship between the cultivated land change and of the Yangtze river delta economic developed regions economic development also made the positive such as arable land loss and economic development exploration, and achieved some research results relationship of quantitative analysis, verify the [2-3].At present, scholars generally agree that the existence of similar kuznets curve [7].How to This contribution has been peer-reviewed. https://doi.org/10.5194/isprs-archives-XLII-3-W10-1013-2020 | © Authors 2020.

  • Jiyuan: Landscape, Inscriptions and the Past
    Jiyuan: landscape, inscriptions and the past Barend J. ter Haar (Oxford University) With the support of the SSHRC a small group of scholars and graduate students went to Jiyuan 濟源, in western Henan, to collect inscriptions. The group was certainly successful, both in obtaining better versions of inscriptions that we already knew about and collecting a wealth of inscriptions whose existence had gone unnoticed even by the local staff of the Cultural Affairs Bureau. Our principal purpose was collecting inscriptions on and in the Temple of River Ji (jidu miao 濟瀆廟) and on the Daoist sites of Wangwu Mountain 王屋山. I focus here on doing research and the importance of imagining the past, rather than more concrete (and hopefully original) analytical results. To me thinking through the problem of imagining the past and the wonderful conversations with colleagues, students and local people —as well as some 200 or so late sixteenth century votive inscriptions containing names, places and amounts of the donations—were the most important results of our expedition. Since this kind of experience is rarely preserved, but remains part of our oral lore destined for direct colleagues, local student and relatives, I thought should write down some of my impressions during and after this visit, organized topically. The field team (photograph by Liu Jie) Our lost sense of historical distances and physical effort In terms of modern transport, the city of Jiyuan and its surroundings can no longer be considered peripheral. One can fly into Beijing, Shanghai and Guangzhou from most major airports in the world. From there one changes planes to Zhengzhou, the capital of Henan province, and a further bus or taxi drive of several hours brings one safely to any hotel in Jiyuan.

The results show that under the condition of natural precipitation, water deficit in Henan Province is 240.5mm and falls to 76.3 mm after manual irrigation. The deficit period is concentrated mostly in March ~ June, accounting for more than 65% of annual water deficit. Spatially water deficit is gradually decreasing from north to south, and agricultural irrigation water productivity is relatively high in central China and relatively low in the south and north. Thereby, the region with full irrigation (the south) and the region with large crop water deficit (the north) have a relatively low irrigation water productivity; a certain degree of water deficit (in central China) is conductive to improvement of crop irrigation water productivity. And then the adaptability between regional agricultural water and water resource characteristic shall not be balanced simply based on the degree of crop water deficit, instead, it shall be closely combined with irrigation water productivity.

Based on the mixed complementarity problem model of gas markets with nodes in Henan Province, China, as an example, this paper applies numerical modeling to simulate the efects of social welfare and equilibrium prices on nodes in two scenarios: pipeline integration and pipeline separation. The fndings reveal the following: (1) Pipeline separation yields greater overall social welfare than pipeline integration, with the welfare shifting from gas producers to consumption markets. (2) Pipeline separation lowers the equilibrium consumption prices by driving competition among gas supply sources. (3) Pipeline separation will increase the contribution of natural gas to primary energy.

School of Tourism and Environment, Shaanxi Normal University, Xi’an 710062, China) Abstract: Ecological migration is the process of increasing the population density in the immigration area and transferring the ecologi- cal pressure from emigration area to immigration area. This process may result in significant changes in land use and land cover in the area of immigration and have an important effect on ecosystem services. Therefore, scientifically revealing the effects and differentia- tion mechanisms of ecological migration on ecosystem services is becoming an important issue related to the implementation of the national ecological migration strategy in China. This study employed the Hongsibu District as a typical example of ecological migration. Hongsibu District is located in the central Ningxia steppe and desert steppe areas. Remote sensing data covering five periods from the period before ecological migration in 1995 and after migration in 2000, 2005, 2010, and 2015 was used to measure the value of ecosys- tem services (ESV). A geographical detector model and the value of ecosystem services model were used to diagnose the dynamic mechanism of the effects of land use change on ecosystem services.

    Bo ZHANG Henan University Abstract: In today’s college English teaching, there are often many kinds of diffi- cult problems. Teachers generally attach importance to language education and despise traditional cultural education in the process of teaching. This kind of edu- cation is not conducive to the widespread of traditional culture in China, and hin- ders the inheritance and continuation of traditional culture. In the process of histor- ical development, China’s traditional culture has a long history. If the teaching of English affects the popularization of traditional culture in domestic colleges and universities, it will be a behavior of loss and gain. Therefore, this paper aims to study the heritage of traditional culture in higher English education, and analyzes the existing problems and solutions. Key words: Higher English; Education and teaching; English teaching; Traditional culture DOI: 10.12184/wspiedWSP2516-250006.20190303 With the continuous development of science and technology and the increas- ing economic level in China, the traditional culture of our country has gradually played its own cultural value in the world cultural stage, and has a very profound and extensive impact. But at present, there is still a phenomenon that the education of our country pays attention to foreign cultures and ignoring local cultures. In or- der to improve the incorrect values and ideas of the new generation of teenagers, it is necessary to integrate traditional culture into the teaching of higher English and allow students to continuously understand the unique advantages of the traditional culture in the process of learning English. In this process, teachers can also inte- grate traditional culture and higher English knowledge, so that students can con- About the author: Bo ZHANG (1980-05), male, Han, Zhengzhou, Henan Province, As- sociate Professor, Postgraduate, Research on Cross-cultural Communication.
