The Statistical Significance Test of Regional Climate Change Caused by Land Use and Land Cover Variation in West China

The West Development Policy being implemented in China is causing significant land use and land cover （LULC） changes in West China. With the up-to-date satellite database of the Global Land Cover Characteristics Database （GLCCD） that characterizes the lower boundary conditions, the regional climate model RIEMS-TEA is used to simulate possible impacts of the significant LULC variation. The model was run for five continuous three-month periods from 1 June to 1 September of 1993, 1994, 1995, 1996, and 1997, and the results of the five groups are examined by means of a student t-test to identify the statistical significance of regional climate variation. The main results are： （1） The regional climate is affected by the LULC variation because the equilibrium of water and heat transfer in the air-vegetation interface is changed. （2） The integrated impact of the LULC variation on regional climate is not only limited to West China where the LULC varies, but also to some areas in the model domain where the LULC does not vary at all. （3） The East Asian monsoon system and its vertical structure are adjusted by the large scale LULC variation in western China, where the consequences are the enhancement of the westward water vapor transfer from the east oast and the relevant increase of wet-hydrostatic energy in the middle-upper atmospheric layers. （4） The ecological engineering in West China affects significantly the regional climate in Northwest China, North China and the middle-lower reaches of the Yangtze River; there are obvious effects in South, Northeast, and Southwest China, but minor effects in Tibet.

Interpretation of the west segment of the coastal fault zone in the coastal region of South China based on the gravity data

By systemic processing, comprehensive analysis, and interpretation of gravity data, we confirmed the existence of the west segment of the coastal fault zone(west of Yangjiang to Beibu Bay) in the coastal region of South China. This showed an apparent high gravity gradient in the NEE direction, and worse linearity and less compactness than that in the Pearl River month. This also revealed a relatively large curvature and a complicated gravity structure. In the finding images processed by the gravity data system, each fault was well reflected and primarily characterized by isolines or thick black stripes with a cutting depth greater than 30 km. Though mutually cut by NW-trending and NE-trending faults, the apparent NEE stripe-shaped structure of the west segment of the coastal fault zone remained unchanged,with good continuity and an activity strength higher than that of NW and NE-trending faults. Moreover,we determined that the west segment of the coastal fault zone is the major seismogenic structure responsible for strong earthquakes in the coastal region in the border area of Guangdong, Guangxi, and Hainan.

Systematic Analysis and Optimization of the Agricultural Structure in Ethnic Regions in Northwest Sichuan Province

Based on introducing the basic conditions of the ethnic regions in northwest Sichuan Province,the thesis analyzes its agricultural development status,which can be classified into two aspects--rich natural resources and slow agricultural economic growth.Through the analysis on the agricultural structure of northwest Sichuan Province,it is found that the production efficiency and economic benefits of crop planting in this region are low,animal husbandry,as a major industry in pastoral region,sees high production efficiency,the agricultural production is still at the resource-oriented stage;its agricultural structure is still the farming-pastoral structure relying mainly on animal husbandry,planting is dominated by crop planting and potato planting,animal husbandry mainly produces dairy and beef;the ethnic regions in northwest Sichuan Province is endowed with the advantages to grow crops,beans and fruits as well as to produce beef,mutton and milk,among which,three industries,say fruit,beef and dairy are with increasing location quotient and gradually strengthening industrial comparative advantage,while the location quotient of the other industries is declining and their industrial comparative advantages are more stable.In order to promote the agriculture in northwest Sichuan Province to develop in breadth and depth,the thesis proposes the following measures and suggestions:the first one is to adhere to the development strategy of modern animal husbandry;the second is to appropriately improve the proportion of economic crops;the third is to accelerate the development of green food processing industry.

Sandy desertification trend in western Northeast China Plain in the past 10 years

The west sandy land of the Northeast China Plain is located in the eastern huge sandy belt of mid-latitude in Eurasia and the eastern fringe of desertified land with best bio-climatic conditions in China. With rapid economic development, the deterioration of eco-environment has occurred and the desertification becomes very obvious. The first part of this paper studies the regional differences of landscape patterns and explores the regional differences of desertification. The second part aims to reveal the dynamics of desertification in the 1990s by using NOAA/AVHRR data and thematic data in GIS database. This work lays a scientific basis for the rehabilitation and development of the sandy lands.

Spatial differentiation pattern of interregional migration in ethnic minority areas of Yunnan Province, China

Interregional migration has broad and far-reaching impacts on regional urbanization process in ethnic minority areas of Southwest China.The previous literature of interregional migration paid less attention on the ethnic minority areas with fragile geographical feature and marginal socio-economic context in the developing world due to the dearth of reliable data.Based on the 2015 national 1%population sampling survey at the village/community scale,taking Yulong Naxi Autonomous County,Yunnan Province,China as the case study,this paper analyzed the spatial differentiation pattern.The results showed that:(1)migration in Yulong Naxi Autonomous County exhibited obvious spatial differentiation characteristics in terms of population aggregation,population loss,migration direction,and migration activity;(2)the overall spatial differentiation of migration exhibited a"layer+sector"pattern in Yulong Naxi Autonomous County:the first layer was active areas with net inflows(<20 km from the seat of the county government),the second layer was inactive areas(within 20–60 km of the seat of the county government),and the third layer was a mixed"layer+sector"zone(>60 km to the seat of the county government),comprised of inactive areas and active areas with net outflows;(3)the spatial differentiation pattern of migration was highly correlated with the regional contexts including the regional economic development,regional transportation accessibility and regional social development,while regional physical geographical factors had insignificant relationships with the migration pattern.

Comparative Research on the Economic Development of Xinjiang i n the Perspective of Development of the West Regions

In the context of Development of the West Regions, by using the annual data from 1999 to 2009 in whole China and 12 provinces of the western regions, we analyze the achievements of socio-economic development of Xinjiang Uygur Autonomous Region from 1999 to 2009 as follows: the economic aggregate has increased prominently and the growth rate is increasing ceaselessly; the primary industry, secondary industry and tertiary industry develop evenly, and the industrial structure is incessantly optimized; the quality of economic growth is promoted increasingly and the living standard of people is improved greatly; the primary industry, secondary industry and tertiary industry stride in tandem, and the momentum of growth is strong. We conduct horizontal comparison on the main economic indicators of Xinjiang, 12 provinces of the western regions and whole China, which include GDP and its growth rate, investment of fixed assets, structure of the primary industry, secondary industry and tertiary industry, the industrial added value, GDP per capita, gross retail sales of social consumption, export and import trade, net income per capita of peasants and herdsmen, and general budget revenue. The result shows that although the implementation of the strategy of Development of the West Regions and the economic development of Xinjiang have achieved some remarkable results, there is a conspicuous gap in comparison with the expected effect. The problems existing in the operation of Xinjiang's economy are analyzed as follows: the industrial level is low, and the economic growth mode is yet to be transformed; the disposable income per capita of urban residents grows slowly, and the increasing gap between the urban areas and rural areas has no trend of dwindling; the investment aggregate is very low, and the momentum of economic growth is short. In order to make the central government and 19 provinces and cities offer pointed aid for Xinjiang, promote the implementation of new strategic development of Western China, and promote the better economic development of Xinjiang in the period of the Twelfth Five-Year Plan, we put forward some feasible suggestions as follows: Xinjiang should grasp favorable opportunities and quicken the pace of industrial structural adjustment; continue to open up to the outside world unswervingly, and improve investment environment ceaselessly; strive to maintain the continuous and rapid development of economy, and improve the living standard of people.

Regional Autonomy of China's Ethnic Minorities

The aggregate population of ethnic minorities has never accounted for more than 9 percent of China’s total, currently approaching 1.3 billion. Yet their development and prosperity have always been high on the agenda of the leaders of the People’s Republic. One of the first things Chinese leaders did after New China was founded in 1949 was to conduct large-scale studies to identify the country’s ethnic groups and name them properly, based on scientific

Why Does China Adopt the System of Regional Ethnic Autonomy?

Ethnic autonomous areas have been set up throughout China where ethnic minorities live china practices regional autonomy for ethnic minorities, not other policies. It is the right choice based on China’s basic conditions.
