【摘要】 本文以长江经济带中部重要地区湖北省为研究区，基于2000—2020年的土地利用数据，运用GIS方法、InVEST模型和地理探测器，分析了湖北省的生境质量的时空演变特征和空间分异影响机理。结果表明：第一，湖北省生境质量总体水平较高，但时序上呈现恶化趋势。高质量生境主要分布在十堰市、神农架林区、恩施土家族苗族自治州、宜昌市等山地地区，低质量生境主要分布在襄阳市、荆门市、武汉市等平原地区，与土地利用空间分布格局较为一致。研究时段内武汉城市圈核心区域生境质量显著降低，武汉城市圈周边区域和襄阳市稍有提升；第二，湖北省生境质量空间分异主要受土地利用类型和退耕还林政策影响，建设用地扩张是生境质量下降的主要原因，而退耕还林等政策是生境质量提升的主要原因。此外还受地形、植被、气候和社会经济等因素的影响，影响因子的主要交互作用为双因子增强，自然、社会因素共同决定着土地利用空间格局，从而影响了生境质量。本研究结果可为湖北省的国土空间规划、生态文明建设和可持续发展提供一定的参考。更多还原

【Abstract】 Taking Hubei Province which is an important area in the central part of the Yangtze River Economic Belt as the research area, the study analyzed the temporal and spatial evolution of habitat quality and response mechanism with land-use data from 2000 to 2020 and methods of GIS methods, In VEST models and Geodetector. The results show that: First, the overall level of habitat quality in Hubei Province is relatively high,but it shows a deteriorating trend in time series. High-quality habitats are mainly distributed in Shiyan,Shennongjia Forest Region, Enshi Tujia Autonomous Prefecture, Yichang and other mountainous areas, while low-quality habitats are mainly distributed in Xiangyang, Jingmen, Wuhan and other plain areas, which are more consistent with the spatial distribution pattern of land use. During the study period, the habitat quality of Wuhan Metropolitan Area’s core area significantly reduced, while the surrounding areas of Wuhan city circle and Xiangyang improved slightly; Second, the spatial differentiation of habitat quality in Hubei Province is mainly affected by the type of land use and the policy of returning farmland to forest. The expansion of construction land is the main reason for the decline of habitat quality, and the policy of returning farmland to forest is the main reason for the improvement of habitat quality. In addition, it is also affected by factors such as topography, vegetation, climate and socioeconomics. The main interaction of the influencing factors is the two-component enhancement, and the natural and social factors jointly determine the spatial pattern of land use, thus affecting the habitat quality. The research results can provide a certain reference for territorial and spatial planning, ecological civilization construction and sustainable development of Hubei Province.更多还原
