| 摘 要： | 随着长株潭城市群的快速发展,人类活动导致的土地利用结构及方式改变对生态环境构成了巨大压力。运用G IS和景观生态学方法的土地利用生态风险评价,以长株潭城市群核心区为研究区域,选择湘江岸线为典型样带,建立了基于源与汇景观功能的土地利用生态风险评价指标体系,并构建了评价模型,对生态风险进行了空间分析和综合评价。结果表明,长沙市建成区的土地利用生态风险指数整体最高,株洲和湘潭居次。其中,从城市群建成区向外,风险指数逐渐降低,长沙、株洲、湘潭三市交界处生态风险指数也较低。根据研究区域生态风险状况、变化和分布特征,提出了相应的风险调控策略和管理方法,为实现区域土地利用与生态、社会、经济的可持续发展提供决策依据。

| Abstract: | With the rapid development of Changsha-Zhuzhou-Xiangtan Urban group,the change of land use structure and mode caused by human's activities has formed,a great ecological and environment pressure.The land use ecological risk assessment based on GIS and landscape ecology were used for selecting the typical transect core area of this urban group as the study area,and the Xiangjiang River shoreline as sample belt.Based on the Source and sink theory with the function of landscape ecological risk assessment,the in... |
