摘要
从地域生态系统价值体系出发 ,探讨城市自然、经济、社会综合资本测算的理论和方法。通过综合资本的测算 ,认识和了解自然生态系统为人类社会经济提供服务的价值量 ,以及人类为维护自然生态系统平衡所需的资本投入量。研究表明 ,灵武市的自然资本约占总资本的 1 /3左右 ,牧草地和水域占自然资本总贡献的 97%。工矿、城镇等土地利用方式产生巨大的自然资本负价值 ,其中工矿占 84% ,城镇占 9% ,显然工矿业对当地自然资本的损耗最大。
In order to analyze ecological values of a regional ecosystem, this paper provided a systematic analysis on the value of regional ecosystem services based on the concept of sustainable development in ecological economics. We have not only estimated the natural capital but also the economic capital and social capital in a regional ecosystem. The total capital of 23 ecosystems serves for 9 sub ecosystems. There are several main appraisal approaches that could be used in ecosystem valuation. Because the regional ecosystem services are uncertain, this must be considered a minimum estimate. For the total capital, natural capital contributes to more than 1/3 of human welfare in the regional ecosystem every year, and therefore represents part of the total economic and social value. Sustainable development can only be achieved when natural capital is increased in a regional ecosystem.
