生境调整对丹顶鹤生境适宜性的影响

Impacts of habitat mitigation on suitability of habitat of cranes

以辽河三角洲为例,运用景观生态决策与评价支持系统(LEDESS)模型就生境调整对丹顶鹤生境适宜性可能导致的影响进行了评价。首先介绍了生态适宜性的评价方法(应用LEDESS模型进行评价)及有关生境调整的一些内容;其次,运用LEDESS模型对生境调整可能导致的地表覆盖物、自然生态单元等立地环境以及保护物种生境适宜性等区域生态后果进行了评估,并与现状进行对比分析。

This study adopted Landscape Ecological Decision and Evaluation Support System （LEDESS） to assess the impacts on the habitat of cranes, due to habitat mitigation, taking the Liaohe River Delta as a case study. In this paper, it introduced the assessment tool for ecological suitability （LEDESS model） and some types of habitat mitigation; and then used the LEDESS model to evaluate the impacts on the habitat of cranes, for example impacts on land surface covers, natural ecological unit and habitat stability etc. ; predicted the ecological results ; and finally compared the baseline and the predicted situation of the habitat of cranes and drew the conclusion.
