摘要
为了探索区域生态修复实践中的生态修复决策方法,根据区域生态系统的特点,引入复合系统理论,提出将构成区域生态系统的各要素按照经济、社会、环境的发展需求,各因子相互配合,协作完成生态修复的决策模式。在对中国松花江哈尔滨段15宗滩岛的计算结果显示:属于协调的有长条通滩和太平庄滩,不协调一级的有老殿宫滩和前进滩,其余滩岛均为不协调。根据不同的协调度等级和指标比较,给出了相应的生态修复策略和建议。
A decision model was developed for ecological restoration based on compound system theory with the characteristics of the regional eco-system.The model coordinates the regional eco-system demands and the economic and environmental development.The model was used for 15 islands in the Harbin reach of the Songhua River in China.The results show that Changtiaotong Island and Taipingzhuang Island are coordinated,Laodiangong Island and Qianjin Island are the first degree of non-coordination,and the other islands of the 15 sub-regions are not coordinated.Regional ecological restoration suggestions are given based on the model and index comparisons.
