中文摘要：

空间管制是协调区域土地利用方式、减少土地利用生态环境负面影响的有效手段．本文依据生态学的理论，提出了基于生态因子耐受度和空间信息技术的土地利用空间管制分区方法，并以连云港为例开展了实证研究．论文综合采用专家评判、最大似然分类法、叠置分析方法等首先完成相关生态因子信息提取、分类与数据处理工作，然后构建了基于ArcGIS平台的土地生态利用空间管制分区数据库，并实现了研究区土地生态利用管制分区；随后根据生态因子限制类型制定了相应的管制规则；最后应用叠置分析功能实现了沿海规划建设用地布局生态评价工作．研究结果表明：（1）连云港土地生态利用五级空间管制区域中，一级非管制区面积占总面积的84．38％，二级轻度管制区占11．53％，三级中度管制区占2．60％，四级重度管制区占0．95％，五级极重度管制区占0．54％；（2）不同管制级别反映了不同的土地生态利用限制程度，需制定相应的空间管制规则；（3）应用土地生态利用空间管制分区结果进行研究区沿海规划建设用地布局评价表明该规划方案能够有效的减少对区域生态环境的不利影响；（4）基于空间信息技术的空间管制分区方法实现了土地生态利用管制分级结果的空间显示，为土地利用空间管制分区研究方法以及土地规划评价提供了新的思路．

英文摘要：

Spatial regulation zoning is an effective way in land use development to reduce its negative impact on regional ecological environment. We developed a spatial regulation zoning method based on the ecological tolerance for each land use type using geographic information system （GIS） and applied it to the regulation zoning in Lianyungang City, China. This proposed method includes three steps：（1 ）Identifying ecological limitation elements for each land use type; （2）Data procession and extraction; and （3）Spatial regulation zoning based on established regulation rules associated with the overlay of limitation element maps. Our results indicate that（ 1 ）The whole study area can be divided into five levels of regulation zones：The non-regulation zone （84. 38%, 6328.5km^2 ）, the mild-regulation zone （ 11.53%, 864.8km^2 ）, the moderate-regulation zone （2.60% ,195. 2km^2 ）, the severe-regulation zone （ 0. 95%, 70. 6km^2 ）, and the extremely severe-regulation zone（ 0.54%, 40.8km^2 ） ; （ 2 ） Spatial regulation rules established for each level reflect the corresponding ecological limitation elements for each land use type; （ 3 ） The assessment of the land use planning using our proposed method suggested that the scheme of our proposed method is suitable for the regulation zone to effectively reduce the negative impact of land use development on the regional ecosystems;and （4）GIS-based spatial regulation zoning provides an effective framework in land use planning to assess the spatial characteristics of the potential ecological impacts of the land use development.
