摘要:

生境质量是人类福祉和社会可持续发展的重要基础。以共和盆地2000、2010、2020年土地利用数据为基础,应用InVEST模型分析生境质量的时空变化,使用PLUS模型模拟不同发展情景下2030年生境质量的空间格局,并探究区域生境质量的影响因素。结果表明:(1)2000—2020年共和盆地土地利用类型主要为草地和未利用地,草地面积整体增加,未利用地显著减少。生境质量整体呈现中部低四周高的分布格局,近20年来呈先增加后下降趋势。(2)自然增长、生态保护和城市扩张情景下2030年的生境质量指数分别为0.5332、0.5369、0.5309,生态保护情景下林地、草地面积较多,更有利于研究区生境质量改善。(3)土地利用是共和盆地生境质量变化的主导因素,其次为土壤类型和NDVI,建设用地扩张是近10年来区域生境质量降低的主要原因。

Abstract:

Habitat quality was an important basis for human well-being and the realization of sustainable development. Based on the land use data in 2000, 2010 and 2020 of the Gonghe Basin, the InVEST was applied to analyze the spatiotemporal changes in habitat quality, and the PLUS model was used to predict the spatial pattern under different development scenarios in 2030, and to explore the driving factors of regional habitat quality. The results show that: (1) From 2000 to 2020, the main land use types in the Gonghe Basin were grassland and unused land, with an overall increase in grassland area and a significant decrease in unused land. The spatial distribution pattern was characterized as low in the central part and high around of habitat quality, with a trend of increasing and then decreasing over the past 20 years. (2) The habitat quality index under the natural growth, ecological protection, and urban expansion scenarios in 2030 was 0.5332, 0.5369, and 0.5309, respectively. Under the ecological protection scenario, the area of forest land and grasslands was larger, which was more conducive to the improvement of habitat quality in the study area. (3) Land use was the dominant factor of changes in habitat quality, followed by soil type and NDVI. The expansion of construction land was the main reason for the decline in regional habitat quality over the past 10 years. The results of the study can provide a scientific basis for the ecological protection and sustainable utilization of land resources in the Gonghe Basin.

Key words: land use, habitat quality, InVEST model, PLUS model, multi-scenario simulation, Gonghe Basin
