In the Sichuan province, livelihood security and social development are particularly sensitive to changes in the sloping farmland, due to the region’s large portion of hilly territory and its over-dense population. In this study, we focused on spatiotemporal change of the sloping farmland and its driving forces in the Sichuan province. Sloping farmland areas were extracted from geographic data from digital elevation model (DEM) and land use maps, and the driving forces of the spatiotemporal change were analyzed using a principal component analysis (PCA). The results indicated that, from 2000 to 2015, sloping farmland decreased by 3263 km2 in the Sichuan province. The area of gently sloping farmland (<10◦) decreased dramatically by 1467 km2, especially in the capital city, Chengdu, and its surrounding areas.

  • Pest Management Plan (Approved by CI-GEF Project Agency 2017-11-17)
    Expanding the coverage and strengthening the management of wetland protected areas in Sichuan Province, China Pest Management Plan (Approved by CI-GEF Project Agency 2017-11-17) 1. The Main Purpose of Developing Pest Management Plan As a result of considerable work on removal of alien and invasive species (AIS), CI has developed guidelines for the use of chemical products and a format for a Pest Management Plan (PMP). A PMP is prepared by the Executing Entity when required by the CI-GEF Project Agency to ensure the use of best practice in the control and removal of alien and invasive plants, insects, and animals in compliance with GEF Environmental and Social Safeguards. 1. Brief Introduction of the Project Expanding the coverage and strengthening the management of wetland protected areas in Sichuan Province, China (hereafter shorten as “The project”) aims to expand and strengthen wetland protected areas in Sichuan Province China and also to mainstream biodiversity conservation and sustainable utilization of wetland resources. The project has two main components of which one focuses on strengthening site level management and standard raised for two wetland parks, namely:1） Xichang-Qionghai Wetland Park, and 2) Xinjin-Baihetan Wetland Park. The project doesn’t plan to promote agricultural production or change landscape by planting or transplanting. Accordingly, it has no attempt to use chemical pesticides. In the two wetland parks, farmers’ land rights have been requisitioned by local governments and agriculture have been totally given-up. Around the two wetland parks especially Xichang-Qionghai, farmers still plant cash crops and use peptides heavily.

China. 3 Email: [email protected] Keywords: Zigong, geopark, sustaining, local community Abstract: Zigong UNESCO Global Geopark is well known for its dinosaur findings and vertebrate fossils of the Middle Jurassic Period and a salt mine of the Triassic Period. It was recognized as member of the Global Geoparks Network in February 2008 and revalidated in December 2012. After the Administration for Zigong UNESCO Global Geopark submitted an extension application to UNESCO in November 2015, a new geopark territory was approved, which is 2720% larger than the area initially defined. More geological heritage as well as natural and cultural heritage has been included in and the increased number of communities of the territory is actively involved in the management and development of the geopark. Zigong UNESCO Global Geopark cooperates with those communities as to encourage geotourism with the help of inspiring local enterprises, creating new jobs and offering high quality training courses. The connection between Zigong UNESCO Global Geopark and communities have been gradually improved. So far, it has been proved that the geopark could not only support local sustainable development but also help local people to acquire earth knowledge as well as to improve their lives. 1 INTRODUCTION However, as stated by the Statutes of the International Geoscience and Geopark Programme Zigong UNESCO Global Geopark (UGGp) is (IGGP) and the Operational Guidelines for located in Zigong Municipal City, Sichuan Province, UNESCO Global Geoparks (UNESCO, 2016), Southwest of China.

Ⅰ. The Main Characteristics of the Urbanization Development in Sichuan The reflection of urbanization in essence is from the industry cluster to population cluster., we tend to divided the process of urbanization into four stages, 1949-1978 is the first stage, 1978 – 1990 is the second stage, 1990 -2000 is the third stage, After the year of 2000 is the fourth stage. In view the particularities of the first phase, this paper researches mainly after three stages. 1. The level of the urbanization enhances unceasingly. With the reform and opening-up and the rapid development of social economy, the urbanization in Sichuan has significant achievements. The average annual growth of the level of urbanization is 0.8 percent in the twelve years of the second stage. The average annual growth in the third stage and the four stages is individually 0.5 and 1.3 percentage. The average annual growth of urbanization in the fourth stage is faster respectively 0.5 and 0.8 percent than the previous two stages which reflects obviously the rapid rise of the urbanization after the fourth stage in Sichuan.

Mycosphere 5(1), 27–76, Doi 10.5943/mycosphere/5/1/2 Abstract A total of 36 species of Hypogymnia are known from southwestern China. This region is a center of biodiversity for the genus. Hypogymnia capitata, H. nitida, H. saxicola, H. pendula, and H. tenuispora are newly described species from Yunnan and Sichuan. Olivetoric acid is new as a major lichen substance in Hypogymnia, occurring only in H. capitata. A key and illustrations are given for the species known from this region, along with five species from adjoining regions that might be confused or have historically been misidentified in this region. Key words – Lecanorales – lichenized ascomycetes – Parmeliaceae – Shaanxi – Sichuan – Tibet – Yunnan – Xizang. Introduction The first major collections of Hypogymnia from southwestern China were by Handel- Mazzetti, from which Zahlbruckner (1930) reported six species now placed in Hypogymnia, and Harry Smith (1921-1934, published piecewise by other authors; Herner 1988). Since the last checklist of lichens in China (Wei 1991), which reported 16 species of Hypogymnia from the southwestern provinces, numerous species of Hypogymnia from southwestern China have been described or revised (Chen 1994, Wei & Bi 1998, McCune & Obermayer 2001, McCune et al.

Results reveal that the rupture process of the Lushan MS7.0 event to be simpler than that of the Wenchuan earthquake and also showed significant differences between the two rupture processes. The whole rupture process 19 lasted 36 s and most of the moment was released within the first 13 s. The total released moment is 1.9×10 N m with MW=6.8. Rupture propagated upwards and bilaterally to both sides from the initial point, resulting in a large slip region of 40 km×30 km, with the maximum slip of 1.8 m, located above the initial point. No surface displacement was estimated around the epicenter, but displacement was observed about 20 km NE and SW directions of the epicenter. Both showed slips of less than 40 cm. The rup- ture suddenly stopped at 20 km NE of the initial point.

Exploring this spatial association and dependence is conducive to the implementation of effective and coordinated policies for regional level CO2 reduction. This study calculated CO2 emissions from 2005–2016 in the Chengdu-Chongqing urban agglomeration with the IPAT model, and empirically explored the spatial structure pattern and association effect of CO2 across the area leveraged by the social network analysis. The findings revealed the following: (1) The spatial structure of CO2 emission in
