    Reconstruction of the spatial pattern of regional habitat quality can revivify the ecological environment background at certain historical periods and provide scientific support for revealing the evolution of regional ecological environmental quality. In this study, we selected 10 driving factors of land use changes, including elevation, slope, aspect, GDP, population, temperature, precipitation, river distance, urban distance, and coastline distance, to construct the CA-Markov model parameters and acquired the land use spatial data for 1975, 1980, 1985, 1990, and 1995 by simulation based on the land use status map for 2010. On this basis, we used the InVEST model to reconstruct the spatial pattern of habitat quality in the study area and conducted classification division and statistical analysis on the computed habitat degradation degree index and the habitat quality index. (1) The results showed that from 1975 to 2010, the habitat degradation degree gradually increased, and the habitat degradation grade spatially presented a layered progressive distribution. Habitat quality presented a constantly decreasing trend. The high-value zones were mainly distributed in the mountainous areas, while the low-value zones were mostly located in built-up areas. During the period of 1975-2010, low-value zones gradually expanded to their surrounding high-value zones, and the high-value zones of habitat quality tended to be fragmented. (2) The spatial-temporal variation characteristics of habitat quality from 1975 to 2010 showed that the regions with low habitat quality were difficult to be restored and mostly maintained their original state; the regions with poor habitat quality, which accounted for 6.40% of the total study area, continued to deteriorate, mainly around built-up areas; the regions with good and superior habitat quality, which accounted for 5.68% of the total study area, were easily converted to regions with bad or poor habitat quality, thus leading to the fragmentation of the regional habitat. (3) From 1975 to 2010, land use changes in the study area were significant and had a huge influence on habitat quality; the habitat quality in the study area decreased consistently, and the area of the regions with bad and poor habitat quality accounted for more than 60% of the total study area. Construction land was the largest factor threatening habitat quality.

    1 Introduction

    With the further intensification of human activities, their interference with the ecosystem affects the quality of biological habitats and leads to the degradation of biodiversity. Currently, with the rapid development of China's urbanization, the sharp expansion of impervious grounds is significantly influencing regional habitat quality, with considerable challenges for biodiversity protection (Brandt et al., 2014; Yuan et al., 2017). Habitat quality refers to the ability of an ecological system to provide living conditions that are suitable for the sustainable development of individuals and populations, reflecting the status of regional biodiversity to some extent (Fellman et al., 2015; Hillard et al., 2017). Habitat quality also reflects the health status of an ecosystem and plays an important role in maintaining the biodiversity level (Dominique et al., 2018; Barbara and Stefan, 2018). In the past few decades, human activities have led to habitat disappearance and fragmentation as well as to habitat quality degeneration, with serious consequences for biodiversity and human welfare (Haddad et al., 2015; Newbold et al., 2015). Land use change reflects the intensity of human activities, which is the most important threat factor of habitat quality (Otto et al., 2016; Lohse et al., 2008). In this sense, it is of great significance for regional biodiversity conservation and the sustainable use of land resources to explore changes in regional habitat quality and to analyze the spatial distribution characteristics of habitat quality degradation based on land use change.
