Temporal and Spatial Changes of Habitat Quality and Their Potential Driving Factors in Southwest China

Climate change and human activities have considerably changed the spatial patterns functional elements of regional habitats. Understanding spatiotemporal changes in habitat quality (HQ) their potential driving factors is essential for maintaining ecosystem health protecting biodiversity. To explore effect physical on HQ Southwest China, we firstly analyzed land-use intensity (LCI). We then evaluated based InVEST model explored heterogeneity main a geographical detector weighted regression model. The results showed that LCI had obvious differences, from low-quality to high-quality (LCI1) was significantly higher than (LCI2). improved steadily China 1990–2015, showing trend low–high–low southeast northwest. Moreover, there were twelve factors, including aboveground biomass, ecological land area ratio, population density, slope, etc., which significant impact differences HQ, effects different observable heterogeneity. LCI2 difference greater LCI1. These suggested current protection management policy positive improving HQ. Our study provides an important decision-making reference sustainable development utilization restoration.
