“…Classifying high spatial resolution aerial imagery using remote sensing analysis is an efficient way to get accurate land cover maps. The use of remote sensing techniques for land-use analysis in some areas has been examined in many studies [ 30 , 36 , 48 , 49 ]. The CART decision tree classification was utilized to classify the processed image.…”

“…The basic principle of this method is to obtain the degree of habitat degradation by calculating the negative impact of threat factors on the habitat and then to calculate the habitat quality with the appropriate conditions of the habitat and the degree of degradation. The formula for calculating the degree of habitat degradation [ 30 , 52 ] is as follows:

where D xj is the degree of habitat degradation of grid x in land-use type j ; ω r is the weight of threat factor r , which indicates the relative degree of damage to the habitat by the threat factor; r y is the intensity of threat factor y ; β x is the resistance of the habitat to external interference; S jr is the relative sensitivity of the habitat to threat factors; i rxy is the influence of threat factor r in grid y on grid x ; R is the total number of threat factors; Y r is the grid number of threat factor r ; d xy is the distance between grid x and grid y ; and d r max is the maximum interference radius of threat factor r . The degree of habitat degradation is between 0 and 1.…”

“…Restoring aquatic vegetation and improving water quality are the fundamental ways to promote fish stock recovery [ 26 ]. Second, these studies conducted regional habitat quality assessment and its influencing factors, such as the impact of urban expansion on habitat quality and the impact of human activities [ 30 , 31 ], or land-use changes on habitats in nature reserves [ 32 , 33 ]. Similar studies have shown that humans can degrade regional habitat quality [ 32 ].…”

“…For instance, Bai et al analyzed the spatial and temporal characteristics of the landscape pattern and habitat quality in Changchun City using spatial analysis and ecological models based on land-use data. The study shows that urbanization development and construction will seriously threaten the regional habitat quality [ 30 ]. The research of Hamilton et al in Australia shows that population growth and agricultural and mining development have severely degraded the local vegetation and threatened habitat quality [ 35 ].…”

“…From the perspective of research methods, at this stage, scholars are using models more often to study habitat quality. For example, the EQI (Eco-environmental Quality Index) model [ 36 ], InVEST [ 30 , 31 , 32 , 33 ], and other models are used for regional habitat quality evaluation. The InVEST model has the advantages of relatively low data requirements and highly visible calculation results.…”

Human activities such as deforestation and urbanization have affected the regional habitat quality of the Poyang Lake area. To evaluate the evolution of habitat quality and its influencing factors in the area, we used Classification and Regression Trees (CART) to interpret the land-use status and used the InVEST (Integrated Valuation of Ecosystem Services and Tradeoffs) model to analyze the characteristics of changes in habitat quality in the Poyang Lake Eco-Economic Zone (PLEEZ) from 1988 to 2018. The results show that, from 1988 to 2018, land use in the PLEEZ underwent significant changes. The changes in land use led to a gradual increase in habitat degradation and a gradual decrease in habitat quality in the study area. Rapid urbanization notably decreased the habitat quality in the study area. However, at the same time, the ecological protection projects such as returning farmland to forests slowed the decline in habitat quality. Driven by these two factors, habitat quality in the PLEEZ gradually declined but the rate of its decline was suppressed. The findings of this study are of great significance for the coordinated development of social, economic, and ecological development in the PLEEZ and similar areas.

Which impacts more seriously on natural habitat loss and degradation? Cropland expansion or urban expansion?

Natural habitat plays an important role in maintaining biodiversity. Both cropland expansion and urban expansion have an influence on natural habitat. However, it is not clear which one impacts more seriously on both the quantity and quality of natural habitat. This study compared the impacts of cropland expansion on the quantity and quality of natural habitat in China between 2000 and 2015 with the impacts of urban expansion. Map algebra in ArcGIS 10.6 was used to calculate the changes in the quantity of natural habitat, while the Integrated Valuation of Ecosystem Services and Trade‐offs (InVEST) Habitat Quality model was used to assess the changes in its quality. The results indicated that cropland expansion led to a loss of 35,811 km2 of natural habitat, which was twelve‐times as much as that from urban expansion. Furthermore, the area of the heaviest habitat degradation due to cropland expansion was 9,530 km2, which was eight‐times as much as that due to urban expansion. Noticeably, the greatest impacts of cropland expansion on natural habitat mostly occurred in areas where the ecological environment is already vulnerable (namely, the resistance and resilience of ecosystems in response to external interference are weak), whereas the impacts of urban expansion were much less in these areas. This study highlights that the impacts of cropland expansion on both the natural habitat loss and degradation far exceeded the impacts of urban expansion. It is necessary to improve cropland protection policies to guarantee food security while ensuring little or no harm to natural habitat.

Changes in land use impact the landscape pattern and habitat quality (LPHQ) of ecosystems. Since 1999, the Grain‐for‐Green Program (GGP) has brought dramatic changes in land use in Western China. Although many studies have reported positive contributions of the GGP to sediment reduction, the effects of the GGP on LPHQ remain unclear. This study aimed to assess the spatiotemporal characteristics of LPHQ in the Xiaolangdi Reservoir Area in China (XRAC) before and after GGP implementation (in 1990, 2000, 2010 and 2020) using the InVEST habitat quality model. The results showed that: (1) From 1990 to 2020, the main land use changes in the XRAC were a 34.97% increase in forestland and a 37.56% decrease in farmland. The landscape pattern showed decreased fragmentation and tended toward aggregation, and forestland became the dominant land use type. (2) Habitat quality in the XRAC improved from 0.63 to 0.91 between 1990 and 2020. High‐quality habitat (0.80–1) was observed in 88.24% of the XRAC in 2020. The spatial distribution of habitat degradation decreased overall, with some localized increases; areas with high levels of habitat degradation shrank and aggregated with the concentration of human activities. (3) The spatiotemporal evolution of habitat quality was influenced by both natural factors and human activities; the short‐term improvement in habitat quality in the XRAC was significantly related to the increase in forestland area, decrease in farmland area, and increase in vegetation coverage. Our results provide evidence for assessing the ecological benefit of the GGP in the Yellow River basin.
