Use a Spatial Analysis Model to Assess Habitat Quality in Lashihai Watershed

摘要: Habitat quality assessments are of great significance for protecting biodiversity. This study analyzes the changing habitat Lashihai watershed based on SPOT satellite images. We extracted land use data in Yunnan province years 2000 and 2015, then used an InVEST model to evaluate degradation, scarcity area from 2015. Spatial statistical methods were determine changes spatial dynamics. Results indicate that number areas with degradation was generally small, both degree had fallen noticeably during fifteen-year period. In general, habitats maintained or improved, while decreased only a few areas. The cultivated increased, tension between people relatively prominent. reason has improved can be attributed three factors: 1) policy returning farmland forests since been well implemented achieved remarkable results. Loss logging deforestation basically eliminated, progress made restoring ecological environment. 2) High background value suitability benefits research area's high vegetation coverage. 3) development local tourism economy transformed advantages into economic bonus, greatly increasing income level living standards residents. At same time, resource bonus increased enthusiasm residents protection helped promote eco-systems, reducing improving quality. conflicts should addressed. Support is needed continuously further residents' income. There must less reliance industry pressure people, all ensuring ecology more forward together sustainable way.
