Spatiotemporal Pattern Study on Biodiversity Maintenance Service of Shiyang River Basin in 1995—2015
摘要
Abstract
The study of biodiversity maintenance service and their spatial patterns in habitats is one of the important fields for biodiversity conservation in the future. Based on the habitat quality evaluation model of InVEST and landscape diversity index, this study takes the Shiyang River Basin in Gansu as the research area, and comprehensively evaluates the biodiversity maintenance service in 1995—2015. On this basis, the spatial pattern analysis is carried out by using Getis-Ord statistical index. The results show that the biodiversity maintenance function is the best in Qilian Mountain area, followed by plain area of middle reaches, worst in plain and desert area of downstream. There is a clear boundary between cold and hot zones, and there is a space synergy relationship. Areas with the biodiversity maintain service score greater than 0.5 are less than 50％ of the basin area, and the increase of human activity intensity is the main reason, and the protection situation is very seriously insufficient. Therefore, it is imperative to develop appropriate management policies and implement biodiversity conservation measures.关键词
