北京山区蒲洼小流域综合治理可持续发展评价与分析

 为北京市山区生态环境建设、防沙治沙工程的实施和可持续发展提供决策参考,以蒲洼小流域为研究对象,提出了适用的、可操作的、简化的小流域综合治理可持续发展指标体系。该指标体系由目标层、类目指标层、项目指标层和指标变量层构成。目标层为小流域综合治理可持续发展度,类目指标层为社会发展能力、经济发展能力和资源环境承载能力。项目指标层为物质需求度、核心发展度、经济富强度、资源丰富度和环境容忍度,指标变量层由16个具体的指标构成。按照从低层到高层的次序,逐层计算各项指标值,最终得出小流域综合治理可持续发展度的指标值。对不同年度蒲洼小流域可持续发展进行了科学的评价与分析。

Evaluation and Analysis of Sustainable Development of Puwa Small Watershed Comprehensive Management in Beijing Mountainous Area

Applicable, operative and simplified indicator system frame for sustainable development of Puwa small watershed comprehensive management was brought forward. This indicator system was composed of goal layer, category indicator layer, item indicator layer, and indicator variable layer, totally including 16 concrete indices. Small watershed sustainable development degree was used to describe the sustainable development ability and level of its comprehensive management. It was composed of social development capacity, economic development capacity, and resource and environment carrying capacity. Social development capacity was composed of material demand degree and core development degree. Economic development capacity was reflected by economic wealthy degree. Resource and environment carrying capacity was composed of resource richness degree and environment endurance degree. According to the sequence from indicator variable layer, item indicator layer, category indicator layer to goal layer, every indicator value in every layer was calculated out, the indicator value of sustainable development degree of small watershed comprehensive management was eventually computed by using the data from Puwa typical small watersheds under the direction of sustainable development theory. Puwa small watershed sustainable development in different years was scientifically evaluated and analyzed.
