Northwest Loess Tableland Area Population, Economy And Resource Environment Coordinated Development Path

Population, economy, resources environment harmonious development is one of the hot issues in today’s world attention. This article to the northwest loess tableland area machine as the study area, analyzes its population, economic and environmental resource coordination degree, and the county for the coordinated development way to propose the countermeasure and the suggestion. Sets the tableland economic development is relatively slow, ecological also is vulnerable. And in today’s social background, the economic development has become inevitable, how in the course of economic development does not damage the ecological environment, even on the ecological environment for certain improvement has important meaning for the region.This paper in reference on the basis of previous studies, using Markway statistical analysis, geographic information system space statistical analysis software, the comprehensive utilization of statistical data, layer data, field investigation data and so on many kinds of data sources, to ecological a theory, population, economy and environment system coupling theory, resources sustainable development theory theory as the guide, by loess tableland area platform for example, with the relation between human and land evaluation as the core, in order to realize the loess tableland sets the population, economic and environmental resource, harmonious and sustainable development for the purpose, from Taiwan tableland area of the subsystems of the development of the development of the state, between system coupling coordination degree and Taiwan tableland area resources environment bearing pressure three levels, from time and space two angles and discussed, at last, combined with the advantages and problems in development, it is in the coordinated development of this strategy and countermeasures. The main conclusions are as follows:1. The loess tableland area whole sets the relation between human and land dynamic change characteristics:(1)System comprehensive index dynamic changes show that, with the reform and opening30years of development, the population and economic system comprehensive index growth trend obvious, especially the1999since the western development, economic comprehensive index of0.35growth by1978from to0.81in2010, a growth of about2.3times; Resources and environment system comprehensive index were significantly reduced tendency, especially in the1990s the greatest reduction, in the21st century, the decline was contained, but volatility is bigger, still have the deteriorating of the crisis.(2) From the system ecological location value dynamic change to see, in the development initial period in high value for resources niche of environmental niche, and ecological economy in a minimum level, the early show that low level of economy, resource development some limitations. With the reform development, population and economic system niche is volatility increased, and resources environment niche were volatility drop, found that economic development is much more attention, but in1999years, the change trend is not obvious, three ecological location value fluctuates up and down in0.33.(3) According to system coupling dynamic change can see the harmony degree, population, economic and environmental resource system overall coupling fluctuations is small, and since1978has been in a state of disorder, in recent years increased slightly; And the system of the coupling between two two coordination degree were wave rise.2. Loess tableland area sets the status quo of the development of space difference:(1) The system present situation of the development of the composite index space distribution said the current situation of the development of the region, including population development level and the level of economic development correlation is very big, high value area located mainly in xian, furthermore, an urban area of xianyang,, and at the same time these areas in the most comprehensive environmental resources of index of low value area; Population, economic development level are not high, and the ecological index of obviously low area mainly located in HanChengShi and Xian Yang qian county, the LiQuan, WuGongXian nearby; While the population, economic development and ecological index has fallen low area are mainly is the Whitewater, weinan city, and Yang, electrical big li and pucheng county, etc.(2)System ecological a value represents the regional development process of the system by the attention by the degree of influence or negative, the ecological location value is in development planning that low need in the aspects of lay particular stress on. Need of economic development as the primary development goals, and Yang is whitewater, big li yicheng city and pucheng county, the second is, zhouzi county, have LinWeiOu, HuaXian and XianYangShi YongShouXian of qian county, LiQuanXian etc, regional; Will the ecological environment and the need to repair as a primary target area, the including except the whitewater, and Yang, yicheng city, big li, pucheng county and other loess tableland area zhouzi county machine.3. The loess tableland area northwest machine resources environment bearing status:Northwestern loess tableland area a dense population, resources and environment to bring a lot of pressure. Although in1999since the implementation of the development of the western region, the condition of the land overload some relief, but the future of the decrease of the cultivated land driving force still exist, and the future, the supply and demand of food situation is still serious, the relation between human and land will be more hasten is acute. The water resources quantity is not rich, even in many areas shortages, which has become a local area in the social economic development and environment construction important restriction, so the future development of the urgent need to stop water consumption growth. Because of the loess tableland Taiwan weinan area, need to greatly increase the vegetation coverage, control of soil erosion.4. Loess tableland area a coordinated development wayLoess tableland area, coordinated and sustainable development of both opportunities and challenges, in the process of development, to follow the economic principle, key breakthrough principle, regional ecological principle, principle, the compensation principle. Taking economic construction as the center, to speed up the adjustment of industrial structure; To guarantee and improve the livelihood of the people, the coordination of urban and rural development as a whole; Promote regional coordinated development; Reasonable use development resources, protecting the environment.The innovation of this paper lies in:first,the innovation of the study area, northwestern loess tableland area machine is a special area, less the previous studies. The second, the method chosen niche on the posture of the model to evaluate regional population, economic and environmental resource coordination between the degree, we can see that each system in the area in the development of the position, in developing policy of lay particular stress on degree or resources environment the damage degree, get system evolution mode. Thus found that area of the weak link, for further provide the basis of comprehensive, coordinated and sustainable development.
