摘要:
为明确人类活动对生态保护重点区域分布的影响,以新疆阿克苏市和温宿县为例,利用生态系统服务和权衡的综合评估(InVEST)模型提取生态源地;然后,使用地理空间数据模拟研究区内人类活动的范围、强度和当地自然条件,创建自然景观阻力面和人类活动阻力面,并依据设立的4个情景分配权重,得到4个综合阻力面;最后,使用Linkage Mapper插件识别各自生态保护重点区域,并对4个结果进行比较.结果表明:人类活动对生态保护重点区域分布存在影响,尤其在人类活动强度较高的城镇中心区,随着人类活动阻力占比增加,周边生态廊道的数量和位置发生显著变化,总面积保持不变;作为生态廊道的一部分,生态夹点随着廊道位置的变化而变化,总面积不变;生态障碍点修复阈值范围缩小,修复产生的最大价值降低.
Abstract:
In order to clarify the impact of human activities on the distribution of ecological protection key area, taking Aksu City and Wensu County in Xinjiang as examples, the ecological source is extracted by using integrated valuation of ecosystem services and trade-offs(InVEST)model. Geospatial data is used to simulate the scope, intensity and local natural conditions of human activities in study area, and natural landscape resistance surfaces and human activity resistance surfaces are created. According to the four established scenarios, four comprehensive resistance surfaces are obtained. The Linkage Mapper plugin is used to identify the respective ecological protection key area and the four results are compared. The results show that human activities have an impact on the distribution of ecological protection key area, especially in the urban central area with high intensity of human activities. With the increase of the proportion of human activity resistance, the number and location of surrounding ecological corridors have changed significantly, and the total area remains un-changed. As a part of the ecological corridor, the ecological pinch changes with the location of the corridor, and the total area remains unchanged. The threshold range of ecological barrier restoration reduces, and the maximum value of restoration declines.
