摘要： 以GIS/RS为技术手段，从景观结构因子、河流及道路密度、湿度指数、地貌条件、耕地生产力5方面对东北地区湿地恢复潜力进行空间分析，确定了东北地区湿地恢复的优先、次优先区域，并利用农作物生产与湿地协调发展指数、景观指数验证恢复效果.结果表明：东北地区湿地优先恢复面积为1.78×10⁶ hm²，其中，耕地和草地为主要的恢复类型，占优先恢复面积的96.7%，主要位于东北部的三江平原和中部的松嫩平原；次优先湿地恢复面积为1.03×10⁶ hm².经过优先、次优先湿地恢复，东北地区湿地面积将在现有湿地面积的基础上提高37.4%.湿地恢复后，研究区农作物生产与湿地协调发展水平值从恢复前的0.539增加到恢复后的0.733,湿地景观格局更有利于沼泽湿地生态功能的发挥.说明基于空间分析制定的东北地区湿地恢复方案是可行的，可为东北地区湿地恢复的实施和生态环境的改善提供数据支持.

Abstract: By using GIS/RS technology, and from the aspects of landscape structure, river and road densities, wetness index, geomorphology, and cultivated land productivity, a spatial analysis was made on the potentiality of wetland restoration in Northeast China, with the regions of priority and secondary priority restoration wetlands determined. Then, by using the coordinated development index of crop production and wetland as well as the landscape indices, the wetland restoration effect was verified. In Northeast China, the wetland area of priority restoration was 1.78×10⁶ hm², among which, farmland and grassland were the main types for restoration, accounting for 96.7% of the total, and mainly located in the Sanjiang Plain in the northeastern part and the Songnen Plain in the central part of Northeast China. The wetland area of secondary priority restoration was 1.03×10⁶ hm². After the restoration of the wetlands, the wetland area in Northeast China would be increased by 37.4%, compared with the present wetland area, and the value of the coordinated development index of crop production and wetland would increase from 0.539 before restoration to 0.733 after restoration. The landscape pattern would be more benefit to the performance of the ecological functions of the wetlands. This study revealed that the restoration scheme of the wetlands in Northeast China based on spatial analysis was practicable, which could provide data support for the implement of wetland restoration and the improvement of ecological environment in Northeast China.
