Abstract:

Practicing a win-win strategy between economic development and ecological protection is a challenging issue worldwide. With the development of economy and social civilization, the intensity of human activities that affects the quality of regional habitats show in different degrees. Particularly, in the developing areas, this effect is often negative, so it is of great significance to practice the combination of economic development and habitat protection in the densely populated and developing areas. Taking the Yellow River Basin (Henan section) as a study example, the spatial and temporal evolution of habitat quality in this region from 2000 to 2021 (historical period) were analyzed based on the habitat quality module of InVEST and the PLUS models. Furthermore, the habitat quality in 2025, 2030, 2035, and 2040 was predicted with an interval of 5 years. The results of the study showed that: (1) the mean value of habitat quality during the historical period decreased by 0.05, showing a decreasing trend. The areas of high habitat quality were concentrated in the southwestern and northwestern mountainous areas, showing a distribution pattern of high in the west and low in the east. (2) During the historical period, 44.74% of the study area experienced a significant decline in habitat quality, mainly occurring in urban and rural construction and road expansion areas. This trend was the most prominent in the western mountainous areas. 33.81% of the study area experienced a significant increase in habitat quality, mainly occurring in the eastern cropland areas and western forested areas. The trend of habitat fragmentation in the study area enhances during the period, and the natural elements such as elevation and vegetation have significant impacts on the regional habitat quality, which is positively correlated with the habitat quality. (3) The future habitat quality patterns under different land use scenarios from 2025 to 2040 differ significantly, with an upward trend in the ecological protection scenario and a slight increase in the mean value of habitat quality in the arable land protection scenario. It also shows a significant downward trend in the mean value of habitat qua-lity in the urban development scenario and a significant impact of human activities on the quality of regional habitats under different development scenarios. This study provides further understandings on the development trend of regional habitat quality and its response to land use changes.
