Karst Area Small Watershed Sustainable Development Evaluation And Policy Options

Can world achieve sustainable development, in the current world, the future of human society is facing a serious long-term challenge. To this end, people must study the laws of sustainable development worldwide, and to develop in line with the rules and measures. Take the road of sustainable development, the future development of China's own development needs and inevitable choice, and this has been clearly reflected in the "China Agenda 21". And the implementation of the strategy of sustainable development, it is necessary to implement a specific space, that is usually the so-called regional. Regional sustainable development is a national basis for sustainable development. China's extensive territory, and natural conditions vary, uneven regional development, inter-regional dual structure grave and to achieve the sustainable development of countries, conditions and develop targeted regional sustainable development strategies. In short, the Study on Sustainable Development should be large scale from time to time small-scale (from global to regional, and from generation to generation, and in between), from qualitative to quantitative, empirical shift from normative, from the abstract to the concrete, put forward a simple, scientific and reasonable, reflecting the trend of quantitative rules.However, in the "sustainable development" has become fashionable slogan of government departments at all levels at the same time, how to monitor and measure sustainable development in different regions of the current research into the popular theme. At present the regional sustainable development of the study of comparative evaluation, which is the main representative Loess Plateau evaluation system, evaluation system, such as the Qinghai-Tibet Plateau, the Yangtze River Basin evaluation index system, the Huaihe River basin evaluation index system; But through research found that the basin evaluation system research, still exists in a universal phenomenon, which is the study of river basin development and too much attention to the practice of a different period, the temporary difficulties associated countermeasures research, This localized to jump out of this trap, it overlooked a dynamic, from the perspective of development to explore the watershed in the process of developing various elements of the role of the relationship between the various elements of such a relationship, as well as relations with the stage of development of the river basin changes caused by the changes. To promote sustainable development of watershed, it must change its traditional research ideas, that watershed in the process of developing links, in a systematic way of thinking to face we are faced with various problems and the corresponding research tasks. From the existing literature can be seen on the Karst region basin evaluation of the sustainable development study also relatively small. Based on the stone bridge watershed for example, through field investigation and access to the relevant information to the regional economics, natural geography, sustainable development and Watershed Science disciplines, such as sustainable development of the theory as a guide, use of GIS, SPSS, AHP , and other research tools for the Karst region River Basin Sustainable Development Evaluation establish a simple, scientific and reasonable, easy-evaluation index system. Finally, the Karst region for the sustainable development of watershed policy options from population, resources, environment, economic and social aspects of the reasonable suggestions.
