A Study On Regional Environmental Warning--A Case Study Of Qionglai, Sichuan

At present, the destroyed ecosystem and the pollution of the environment gradually become key factors that hinder the development of a region. In order to realize the sustainable development of a region, assessing the coordination and adaptabilities of the regional environment and economic development, early warning the district that have be out of the carrying capacity and the important environmental problems of a region so that people can take essential and pertinence actions, the environmental warning study gradually become one of the hot points in environment science. The paper endeavors to do creative researches on environment warning of the middle and small regions, using Qionglai, Sichuan as researched case, to make the researches in the field to be done more deeply. The paper totally composed of five parts.The first part does research on the status of the early environmental warning home and abroad and analyzes the reason that the study on small-middle dimension environmental warning is done infrequently. The part also presents contents and frameworks of the research and chooses cases studied based on the analysis.In part II, the fruits of the early regional environment-warning' s studies have been summarized and appraised. The paper pointed out that the cores of the environmental warning are the development of a region and the response to environment, that its important contents are the sustainable development ability (SDA) of a region, and analyzing three focuses in environmental warning and relationship of them. At the same time, the part discusses index systems and models of environmental warning that had been used in china.The third part of the paper is about the qualitative analysis on researched regions and presents characteristics of environmental frangibility and internal diversity in researched regions, and then discusses its distinguishing features: the telescoping environmental pollution, the area-pollution in agriculture and the new features of the environmental pollution in city.Part IV establishes index systems and models of the regional environment warning regarding sample areas. The index systems compose of eco-environmental subsystems, social and economic subsystems, environmental pollution and pollution treatment subsystems, which amount to thirty-six indexes, and choose The Analytic Hierarchy (AHP) model as research model.Part V chiefly studies on eco-environmental evaluation of Qionglai, and forecasts its evolvement in future 5-10 years based given indexes and models, and then presents the fifteen-year plan and longtime layouts made by Qionglai government. Finally, the conclusions that eco-environment is evolving well are drawn, which provide decision-making facts for Qionglai's the management of environmental warning.
