摘要

[目的] 以生态环境保护为视角，根据江苏省宜兴市经济发达、生态环境优越的特点，从水土保持和生物多样性保护两方面探讨农村居民点用地布局适宜性，为该区农村居民点规划、整理提供依据。[方法] 基于宜兴市2010年ETM遥感数据、DEM数据和植被覆盖数据，运用最小累积阻力模型得到水土保持和生物多样性保护最小累积阻力面，借助ArcGIS 9.3软件，采用空间叠加分析方法和自然断点法对宜兴市农村居民点用地布局适宜性进行分类。[结果] 宜兴市农村居民点用地可划分为高度适宜、中度适宜、低度适宜、不适宜4种类型，分别占农村居民点用地总面积的57.67%，12.82%，22.83%，6.68%。[结论] 不同适宜程度的农村居民点用地应当分别采取重点发展、适度建设、限制扩张以及优先整治的对策，基于生态环境的农村居民点用地布局适宜性评价能够满足宜兴市农村居民点用地布局中保护生态环境的要求。

Abstract

[Objective] To evaluate the suitability of rural residential land from the perspective of ecological environment protection

this paper took the conservation of water

soil and biodiversity into consideration according to the present characteristics of well-developed economy and superior ecological environment in Yixing City of Jiangsu Province. [Methods] Based on data of ETM

DEM

and vegetation coverage in Yixing City in 2010

the method of minimum cumulative resistance model was used to calculate the minimum cumulative resistance surfaces of water-soil conservation and biodiversity conservation

then the methods of spatial overlay analysis and natural break were used to determine the suitability grades by ArcGIS 9.3. [Results] The suitability of the rural residential land in Yixing City can be divided into four grades: highly suitable

medium suitable

lowly suitable and unsuitable

which accounts for 57.67%

12.82%

22.83% and 6.68% of the total area

respectively. [Conclusion] Suggestions of key development

moderate construction

restricted expansion and prior remediation were proposed at the above mentioned grade of rural residential land. The research results can not only satisfy the requirements of rural residential land layout in Yixing City for the purpose of ecological environment protection

but also can provide some references for the rural residential land layout optimization in other similar area.
