Abstract： In the context of new urbanization development, the coordinated development of economy and ecology in Gonghe County, Qinghai Province, which is a key node in the construction of the Lanxi urban agglomeration and a typical desert area that is ecologically fragile. It is of great significance to China in accelerating the construction a new development pattern and the implementation of the Innovation Demonstration Zone of Sustainable Development Agenda in Hainan Prefecture . Based on the land use data of 2000, 2010 and 2020, this study utilizes the InVEST model to explore the spatial and temporal distribution and effect change characteristics of habitat quality in Republican County from 2000 to 2020, and further investigate the influencing factors and their effects on habitat quality using geographic probes and geographical weighted regression (GWR). The results show that: (1) The overall habitat quality in Republican County from 2000 to 2020 showed an upward trend, and the mean values of habitat quality were 0.612, 0.626, and 0.627, respectively, and there were obvious regional differences in the spatial distribution of habitat quality, and the spatial pattern showed a trend of high in the north and low in the south. (2) The main driving factors affecting habitat quality in Gonghe County were the mean annual temperature (TEM) and normalized vegetation index (NDVI), and the interaction between the factors has a greater influence on the spatial differentiation of habitat quality than a single factor, with TEM interacting strongly with Shannon's evenness index (SHEI) and Shannon's diversity index (SHDI). (3) The GWR model quantified the different driving characteristics and strengths of each driver on habitat quality at the spatial level, with TEM having a negative effect on habitat quality, with the negative effect mainly concentrated in the northern and eastern parts of the republic. The positive effect of gross domestic product (GDP) on habitat quality increased by 30% compared to 2000, and the photovoltaic in Tala Shoal promoted the synergistic development of eco-industry in Gonghe County. The results of the study can provide a scientific basis for decision-making to promote local economic construction and ecological protection in arid areas.The results of the study can provide scientific decision-making basis for promoting local economic construction and ecological environmental protection in arid areas.
