摘要

[目的] 开展土地生态敏感性分区研究，剖析区域不同土地利用方式下土地生态环境状况，为区域土地利用规划等提供依据。[方法] 以苏南地区典型城市宜兴市作为研究区，采用USLE与景观安全格局方法划分水土流失敏感区和生物多样性敏感区，进而得到宜兴市土地利用的生态敏感区。[结果] 宜兴市土地利用生态敏感程度总体较低，一般敏感区与低敏感区面积接近区域总面积68.17%，极敏感区分布集中，敏感等级由南部山区向北部平原逐步降低。[结论] USLE与景观安全格局相结合进行土地利用的生态敏感性分区研究，可以发挥两者的长处，综合和定量分析不同因素对区域生态环境的影响。

Abstract

[Objective] Land ecological sensitive zoning was comprehensively analyzed under different land use type to provide reference for regional land use planning. [Methods] Yixing City

a typical city in Southern Jiangsu Province was taken as an example

its land use ecological sensitive zones were divided according to the zones of soil and water loss sensitivity and biodiversity preservation priority using USLE model and landscape security pattern. [Results] The ecological sensitivity in Yixing City was thought relatively low. The zones with extremely high sensitivity accounted only for 7.87% of the total area

the zones with high sensitivity

moderate sensitivity and low sensitivity covered 23.96%

35.71% and 32.46%

respectively. The zones with extremely high sensitivity were clustered together in space. Sensitivity declined gradually from the southern hill district to the northern plain district. [Conclusion] The application of USLE model combined with landscape security pattern can comprehensively recognize the factors that influence ecological sensitivity

and quantitatively grade the land use ecological sensitive zones.
