摘要
本文主要针对吉林西部供水工程所涉及的部分行政区以及向海、莫莫格、查干湖和波罗湖四个国家级自然保护区补水前后的景观生态格局变化进行分析。结果表明:项目实施前后行政区和各生态区总体景观格局未发生较大变化,其中水域、沼泽等湿地景观优势有所增加,盐碱地景观优势有所降低,但仍以农业生态系统作为区域的景观基底,其他各景观斑块镶嵌其中。本研究为区域内改善湿地景观结构、维护湿地生态环境等工作提供一定的理论依据。
In dais paper, we analyzed the landscape ecological patterns changes of some districts and four national nature reserves, Xianghai, Momoge, Chagan lake and Baluo lake involved in the water supply project in Western Jilin. The results showed that before and after the implementation of the project, there was no significant change in the overall landscape pattern of the districts and the ecological zones. Among them, the advantages of wetlands and swamps were increased, the saline alkali land decreased, and the agricultural ecosystem was still the landscape base of the region, and other landscape patches were mosaic. This study can provide theoretical basis for improving wetland landscape structure and maintaining wetland ecological environment in this area.
