摘要
为了保护临江市生态环境,促进临江市可持续发展,选取土地利用类型、土壤条件、降雨量地形起伏度、植被覆盖度和生态保护区6个敏感因子通过ArcGIS的空间分析技术对临江市生态敏感性进行研究评价.评价结果显示临江市整体生态敏感性较高,中敏感区占比最大,零散分布于临江市全域.基于生态敏感性评价结果,在保证村级行政边界完整的情况下,将临江市划分为5个不同功能类型的生态分区,并对各生态分区提出了不同的发展策略和管控措施,以期为此类生态环境良好、生态敏感性较高的区域制定空间保护策略提供参考依据,为推动生态文明建设奠定基础.
Abstract
In recent years,due to the rapid development of urbanization,Linjiang City had produced a series of ecological and environmental problems.In order to protect the ecological environment and promote the sustainable development of Linjiang City,this paper selected six sensitive factors of land use type,soil conditions,rainfall topographic undulation,vege-tation coverage and ecological reserve to evaluate the ecological sensitivity of Linjiang City through ArcGIS spatial analysis technology.The evaluation results showed that the overall ecological sensitivity of Linjiang City was high,and the proportion of sensitive areas was the largest(42.01％),scattered in the whole area of Linjiang City.Finally,based on the results of ecological sensitivity assessment,Linjiang City was divided into five ecological zones with different functional types while ensuring the integrity of village-level administrative bounda-ries,and different development strategies and control measures were proposed for each eco-logical zone,so as to provide reference for formulating spatial protection strategies for such zones with good ecological environment and high ecological sensitivity.This would lay the foundation for promoting ecological progress.
