“…The regional environment background influences the change in regional habitat quality. In areas with fragile ecological environments, such as semi-arid and arid zones, woodland and grassland are prone to degradation under the influence of harsh environments, which leads to a reduction in area or habitat fragmentation, resulting in the decline of habitat quality (Mengist et al, 2021;Wu et al, 2022). Tacheng is a typical arid region.…”

“…In urban and rural areas, it is necessary to enhance the green landscape in towns and their surrounding areas by building green belts around the cities and raising the standard of the ecological environment in residential areas. Fifth, in the marginal zones of different habitats, such as the desert oasis transition zone and industrial and agricultural fringe areas, the irrational development and utilization of various land types had resulted in serious imbalance of ecological carrying capacity (Wu et al, 2022). In these areas, forest and grass should be restored in time, and ecological shelter belts should be built to improve the regional ecological environment (Liu et al, 2018).…”

Habitat quality assessment is an important basis for ecological restoration practice. Taking the Tacheng region as an example, the InVEST model was used to evaluate the habitat quality of the Tacheng region in five periods from 2000 to 2020, and analyze the reasons for its changes, to provide theoretical guidance for ecological restoration practice in arid areas. The conclusions were that from 2000 to 2020, the habitat quality in the Tacheng region improved slightly, and the value of the habitat index in the Tacheng region was the highest in 2010, which was 0.577, and then decreased slightly. The habitat quality in the Tacheng region was significantly influenced by land use type conversion and precipitation. The change in land use type directly affected the change in habitat quality. The study region is located in an arid area; the forest land and grassland native to the region have more vegetation communities and genera of species and can be self-sustaining and resilient to disturbance, having high scores for habitat quality. The species of arable land is a monoculture; it cannot be self-sustaining and resilient to disturbance, and though it has high vegetation cover, the value of habitat quality is lower than that of forestland and grassland. The vegetation of unused land is rare, and the ecosystem of unused land is sensitive and vulnerable; the habitat quality scores are very low. The conversion of forest land, grassland, arable land, and unused land would directly affect the value of habitat quality, and conversion was the main factor affecting the change in habitat quality. In addition, precipitation was also an important factor affecting the change in habitat quality in the Tacheng region, which affected the biomass of natural vegetation and then affected the habitat quality. The results provided the temporal and spatial change of habitat quality and its driving forces in the Tacheng region, which helps determine appropriate measures and sites in ecological restoration projects.

“…The economic and social development of the Yellow River floodplain area is relatively backward, and the region also faces serious flood threat and ecological protection problems. Therefore, the improvement of local habitat quality can lay a solid green foundation for the ecological protection strategy of the Yellow River basin [ 32 ]; Hao et al, 2022). Fig.…”
“…For long-term HQ monitoring, the model assessment method has a number of advantages over the integrated indicator evaluation method [ 10 ]. The habitat suitability index (HSI) model [ 11 ], social values for ecosystem services (SolVES) model [ 12 , 13 ], and InVEST model [ 14 , 15 ] are examples of common models. The InVEST model assesses biodiversity based on the quantity of the habitat exposed to external threats, which it deems to be the primary factor contributing to the degradation of HQ [ 16 , 17 ].…”
Natural habitats are damaged by human interference to varying degrees during the urbanization process, which can impede a region’s high-quality development. In this study, we examined the spatial–temporal evolution characteristics of habitat quality and urbanization in the Lower Yellow River from 2000 to 2020 using the integrated valuation of ecosystem services and tradeoffs (InVEST) model and the comprehensive indicator method. We also evaluated the coupling relationship between the habitat quality and urbanization using the coupling coordination degree model. The findings indicate the following aspects: (1) Between 2000 and 2020, the Lower Yellow River’s habitat quality was typically mediocre, with a steady declining trend. The majority of cities displayed a trend toward declining habitat quality. (2) Both the urbanization subsystem and the urbanization level in 34 cities have demonstrated a consistent growth tendency. The urbanization level is most affected by economic urbanization among the subsystems. (3) The coupling coordination degree have revealed an ongoing trend of growth. In most cities, the relationship between habitat quality and urbanization has been evolving toward coordination. The results of this study have some reference value for ameliorating the habitat quality of the Lower Yellow River and solving the coupling coordination relationship between habitat quality and urbanization.
