基于生态敏感性的乡村景观分析--以福州市连江县文新村为例

Analysis on Rural Landscape Based on Ecological Sensitivity——TakingWenxin Village as an Example

在乡村发展大背景下,科学评估乡村景观的生态敏感性,合理划分保护或开发使用的区域,维护乡村景观生态的稳定性,是保证人与环境可持续发展的基础。笔者以Arc GIS技术为支撑,选取地形、土地利用类型、水体等3个生态因子作为生态敏感性评价指标,先对单因子进行生态敏感性分析,并采用专家打分法和变异系数法获得权重,依据加权叠加法对文新村生态敏感性进行综合分析,按敏感度强弱划分出高敏感区、较高敏感区、较低敏感区和低敏感区。结果表明:影响文新村景观的主要指标因子为土地利用类型与坡向;河网水系、山地、湿地周边区域的敏感度较高。

Under the background of rural development,it is very important to scientifically assess the ecological sensitivity of rural natural landscapes,rationally divide the areas of protection and development,and maintain the stability of rural natural landscape ecology,which is the basis for sustainable development of people and the environment.Based on the ArcGIS technology,the author selects tepography,land use type and water body as the ecological sensitivity evaluation indicators.Firstly,the ecological sensitivity analysis of single factors is carried out.Then the expert scoring method and weighted superposition method are used to comprehensively analyze the ecological sensitivity of Wenxin Village.Finally,according to the sensitivity,the high sensitive area,the higher sensitive area,the lower sensitive area and the low sensitive area are divided.The results show that the main index factors affecting the landscape of Wenxin Village are land use type and aspect.The sensitivity of the river network,mountain and wetland’surrounding areas is high.
