Spatial variability of glacial changes and their effects on water resources in the Chinese Tianshan Mountains during the last five decades

Changes in glaciers in the Chinese Tianshan Mountains have been analyzed previously. However, most previous studies focused on individual glaciers and/or decentralized glacial basins. Moreover, a majority of these studies were published only in Chinese, which limited their usefulness at the international level. With this in mind, the authors reviewed the previous studies to create an overview of glacial changes in the Chinese Tianshan Mountains over the last five decades and discussed the effects of glacial changes on water resources. In response to climate change, glaciers in the Tianshan Mountains are shrinking rapidly and are ca. 20% smaller on average in the past five decades. Overall, the area reduction of glacial basins in the central part of the Chinese Tianshan Mountains is larger than that in the eastern and western parts. The spatial differentiation in glacial changes are caused by both differences in regional climate and in glacial factors. The effects of glacial changes on water resources vary in different river basins due to the differences in glacier distribution, characteristics of glacial change and proportion of the glacier meltwater in river runoff.

Plant Resources of Miscanthus in Yuncheng Region

Some Miscanthus species are potential plant resources for energy and industry.The three high-growing species which originated in China, i. e. M. floridulus, M. sacchariflorus, M. sinensis, now still distribute--or at least have ever been planted--inYuncheng region, though they are decreasing in their community and individual numbersrapidly in the latest decades due to the human activities such as land exploitation and agriculture. According to our investigation it is clear that Yuncheng region is a transition or overlapping area for various species and geographic varieties of these plants. It is approrpriate tobuild a gene pool in this region to collect and to protect Miscanthus resources.It will be discussed respectively for the three species as follows:

RESEARCH ON THE THEORY AND METHODS OF COMPREHENSIVE EVALUATION OF REGIONAL COAL RESOURCES

consists of forecasting for the total reserves of regional mineral resources and evaluation,compreIn general,based on evaluated objects and factors involved,evaluation of mineral resources hensive evaluation of regional mineral resources, and economic and technical evaluation of deposits. Here a region can be a country, a province, or a mining area, while a deposit is mainly related to a single type of mineral, although it can contain more than one types of minerals. In the past, to assess mineral resources was primarily to evaluate and forecast the total reserves of regional mineral resources. With the advancement of science, technology, and economy, the evaluation of mineral resources has developed from forecasting the reserves of them to comprehensively evaluating them on the basis of numerous factors.

The research of economic development law in resourceful city

The resource advantage of resourceful region has made the region develop very fast. However because the resource is of exhausting character, this means that the region has hidden troubles of economic depression. The paper analyzes the formation of resourceful region and the law of resourceful regions economic development, and then the paper brings forward that the resourceful region has a potential danger of economic depression. Considering Chinas economic development practice, the paper puts forward a basic way of thinking. That is: we must attach importance to the problem of industrial structure when we pay attention to existing resource advantage in order to avoid the simplification of regional industrial structure and to avoid entering a vicious cycle.

Evaluation of ontological value of regional tourism resources:A case study of Hainan Island,China

Evaluation of tourism resources is necessary for tourism regionalization and planning and for the development of tourism destinations.Furthermore,the scientific evaluation of the status of existing tourism resources is important for optimally combining and rationally developing regional tourism resources.In this study,a conceptual model for estimating the ontological value of tourism resources was developed and an evaluation indicator system was designed for the ontological value.On the basis of the quantitative and spatial characteristics of regional tourism resources,six indicators were constructed:quantitative density,richness,dominance,combination,aggregation,and accessibility.Furthermore,spatial differentiation characteristics of the ontological value indicators of county-level tourism resources on Hainan Island were analyzed,and the ontological value of the tourism resources was comprehensively evaluated and ranked by using a fuzzy clustering evaluation method.Finally,the evaluation results were verified on the basis of the quantity,quality,and accessibility of regional tourism resources by using an expert scoring method.The results showed that the test results were consistent with the inferences drawn from the ontological value,indicating that the evaluation indicator system is scientific and reliable and that it is an effective alternative to existing evaluation indexes of regional tourism resources,which are inconsistent.The fuzzy clustering evaluation method overcomes the subjectivity in the evaluation process and is practical for the quantitative evaluation of regional tourism resources.The evaluation indicator system for regional tourism resources designed in this study can provide a reference for the evaluation of the tourism resource development value on a regional scale,and the evaluation results can facilitate informed policymaking for the rational development of regional tourism resources.

A Positive Comparative Study of Regional Human Resources Quality

This thesis appraises the human resources in developed regions, relatively developed regions, moderately developed regions and underdeveloped regions in China by means of comprehensive fuzzy assessment of human resources quality. Then the interrelationship between regional economic development and human resources quality is analysed. The results can be of some value for decision making.

Evaluating Beijing’s human carrying capacity from the perspective of water resource constraints

As the demands on limited water resources intensify, concerns are being raised about the human carrying capacity of these resources. However, few researchers have studied the carrying capacity of regional water resources. Beijing, the second-largest city in China, faces a critical water shortage that will limit the city’s future development. We developed a method to quantify the carrying capacity of Beijing’s water resources by considering water-use structures based on the proportions of water used for agricultural, industrial, and domestic purposes. We defined a reference structure as 45：22：33 （% of total, respectively）, an optimized structure as 40：20：40, and an ideal structure as 50：15：35. We also considered four domestic water quotas： 55, 75, 95, and 115 m 3 /（person·yr）. The urban carrying capacity of 10–12 million was closest to Beijing’s actual 2003 population for all three water-use structures with urban domestic water use of 75 m 3 /（person·yr）. However, after accounting for our underlying assumptions, the adjusted carrying capacity is closer to 5–6 million. Thus, Beijing’s population in 2003 was almost twice the adjusted carrying capacity. Based on this result, we discussed the ecological and environmental problems created by Beijing’s excessive population and propose measures to mitigate these problems.

Cloud model-based analysis of regional sustainable water resource utilization schemes

Given the adverse effects of current water shortages,low utilization and imbalance between the supply and demand,and other status quo problems relating to social economic development,the construction industry and agriculture,a cloud model was applied to a water resource system using five sustainable water resource utilization schemes for Kiamusze,Heilongjiang Province,as an example.This research changes the qualitative description of the concept language into a quantitative analysis of an evaluation indicator.A cloud model-based analytical method for regional sustainable water resource utilization schemes was proposed,and the sustainable grades of the water resources were calculated.The research results showed that,in addition to the natural continuation of such schemes,the development trends of four new schemes achieved the sustainable utilization of water resources,and thus,the sustainable water resource utilization was optimized.However,when the open-source,throttle,comprehensive and coordination schemes were subjected to the optimum applicability analysis,based on the limiting factors in different periods,resource availability and long-term development,decision-making regarding the best solution in different periods better ensures sustainable development in Kiamusze.The research results provide a significant theoretical basis for the formulation of scientific and reasonable sustainable water resource utilization strategies in Kiamusze.
