Habitat Quality Evaluation Based on InVEST Model-A Case Study of Xiaojiang Watershed of Hengduan Mountains
摘要
Abstract
Objective] The aim was to evaluate habitat quality of Xiaojiang watershed of Hengduan Mountains,to provide theoretical support for improving eco-environment and optimizing land use status.[Method] The InVEST model was used to quantify and evaluate the habitat quality in Xiaojiang watershed of Henduan Mountains by using theland use data,including roads,farmlands,cities and towns.In addition,the spatial distribu-tion features and regional differences were analyzed.[Result] The results showed that:① The habitat quality was generally low and the heavily degraded area was in the center of the river basin.②Land use and land cover type had a significant impact on habitat quality,and the strategy of returning the grain plots to forestry and grass had mitigated the deterioration of habitat quality effectively .③ The habitat quality in Xiaojiang wa-tershed showed the heterogeneity of vertical space .The protection of ecological environment and development of social economy should be acted according to local conditions.[Conclusion] The study can provide scientific basis and planning guidance for ecology protection and sustainable development of Xiaojiang watershed.关键词
