The design and implementation of the project are of significance under the macro background of western development of China. By the integrated assessment of western China, we can get the first-hand data covering all the environmental factors as well as disclose the situations and their changing trends of ecosystem in the western part of China, which will benefit the decision-making for the central and local governments in the implementation of the western development strategy. In other words, the implementation of the project, to a certain extent, can guarantee the regional sustainable development of western China.展开更多

In this paper, we will evaluate the effects of the first 10 years' GCWD and use the latest Chinese annual data from 1978 to 2010 to investigate the problem of regional differentials in the development process, evaluate the effects of GCWD policy and test whether there is a regional Kuznets inverted-U curve in the regional development of China. The result shows that there are both good and bad news: the good news is that the inverted U-shaped curve of absolute differential between eastern and western areas finally emerges (the previous studies showed that the inverted-U curve did not appear and the differentials between eastern and western areas became worse) and the bad news is that the differential is in the first half of the inverted U-shaped curve in our choice of time span (1978-2010), that is, it is still in the situation of deterioration, and the turning better point will emerge in 2025. Although the western areas have benefitted from GCWD, the absolute gap has been still widened. To narrow the gap, the western areas should accelerate the industrial development and the government should adjust the policy and make more efforts to support the development of the industry in the western areas, especially cultivate and support the development of the western characteristic and advantageous industry rather than just supporting the construction of infrastructure in the western areas.展开更多

The ecological environment has been seriously damaged by population growth and over-exploitation of natural resources. It is very important for coordinating the regional development and safeguarding ecological security to discuss the eco-environment evolution trend and its sustainable development strategies in Western China. Based on analyzing documents and relative research,the changes of main ecological and environmental problems in the western region,such as degradation of forest and grassland ecosystems,shrinkage of wetland,desertification,water and soil erosion,etc. were synthetically discussed. Then,according to the development trend,some countermeasures for eco-environment protection and rehabilitation and sustainable development were proposed.展开更多

By taking Shawan Hot Spring in Xinjiang for example, the paper had analyzed its natural condition, hot springs and tourist economic development. And then, quantitative and qualitative analysis had been conducted on the quality of water environment resources in the research area. It had analyzed reasons for degeneration of water environment and studied exploitation and sustainable development of hot springs. It was considered that environment especially water environment quality had decreased since hot spring tourism development. In order to achieve sustainable development of hot springs and promotion of local tourism, it must be guided by environment treatment, and some strategies for sustainable development of hot springs had been proposed.展开更多

The results indicate that economic density is positively related to both rural settlements density (R^2=0.73) and rural population density (R^2=0.77), and it is the same for relationship between towns density and rural settlements density (R^2=0.88) and between towns density and economic density (R^2=0.71), and the scattered distribution pattern of the rural settlements and shortage of economic centers is a major factor to the lagged socioeconomic development. On the eco-economic zoning to Daofu County, the paper indicates the spatial distribution model and the industrial development model of the rural settlements need to be changed, and rural population should be concentrated in larger rural settlements with development of off-farm industries while infrastructure construction is to reinforced.展开更多

The three stages are: the stage of surface water development (the first stage), the stage of comprehensive development of surface and ground water (the second stage) and the stage of economical development of water rare (the third stage). The three stages link each other and show the law and processes of water resources exploitation and utilization associated with social and technological progess. The economical water policy should run through the three stages. On this point, however, the third stage differs from the others, particularly, refering to irrigated agriculture. The third stage has more progressive significance because it breaks the traditional ideas on water resources development. According to our investigation and calculation, under present conditions of water resources development, the net used water is about 160 × 108 m3, accounting for 18% of the total water resources of northwestern China. The water resources have not ben fully develop. If the first stage is finished, the exploitable water can be increased by 91 %. After the second stage, furthermore, it can be increased by 216%.展开更多
