城市土地资源生态承载力评价初探

从生态系统功能角度讲,对城市的建设用地生态规模和耕地资源生态承载力评价具有重要的实际应用意义。从实践意义来说,可根据这种评价的结果,为城市确定一个适宜环境的良性发展的人类利用土地资源进行各项经济活动的规模限度,促使城市建设用地在生态可持续条件下进行利用。从建设用地合理生态适宜量比例和耕地资源固碳释氧的角度对城市耕地资源生态效用进行定量研究分析,可为系统研究城市土地资源生态承载力提供参考性的思路。

The Evaluation on the Ecology Carrying Capacity of City Land Resources

The evaluation on the Ecology Carrying Capacity of the city construction land and farmland resources on the basis of the ecosystem function is of important significance for promoting rational use of land resources and sustainable development of the cities.This paper explores the approachs evaluating Ecology Carrying Capacity of the construction land and farmland in the cities.The quantitative analysis and research on the reasonable construction land proportion and farmland scale and its results will provide scientific basis for the systemic study on ecology carrying capacity of city land resource.
