Biodiversity is profoundly influenced by habitat quality, and Harbin, a provincial capital situated in cold climate zone, stands out as one of China’s regions most susceptible to the repercussions change. To ensure city’s continued sustainable growth, thorough assessment quality must be conducted. This study employs comprehensive approach integrating InVEST model, PLUS landscape pattern analysis, geographic detector, geographically weighted regression model. The goal assess how land use have changed Harbin City, investigate factors contributing spatial heterogeneity thoroughly examine evolutionary patterns under inertial development scenario from 2030 2050, propose optimization strategies. There are four key findings. First, 2000 2020, agricultural forest were City’s two prevalent types. notable transition occurred grassland, expansion construction primarily resulted its encroachment into areas. Second, within area study, increased while simultaneously experiencing decrease connectivity, had tendency toward more fragmented distribution. Third, overall rose between 2020 but declined 2050. was “weak west high east” distribution quality. Fourth, population density has impact on with NDVI GDP close behind. Conversely, precipitation slope comparatively smaller influences Natural combined favorable influence across research region terms discernibly detrimental impact. Given these findings, this suggests targeted strategies optimize These recommendations relevant not only for biodiversity conservation also an ecologically community, particularly region.

The resilience of the urban ecological network is an indispensable aspect reflecting recovery capacity after external risk shock. Improving conducive to enhancing benefits. However, current studies are lack evaluation from a comprehensive perspective. Thus, in this study, taking three typical agglomerations as cases, framework was proposed assess resilience. First, we selected reserve sources and combined them with corridors construct network. Then evaluated networks perspectives robustness redundancy. Finally, analyzed under different importance nodes failed. results showed that (1) average values value (CRV) were over than 0.8. (2) blow optimal throughout during period 1985 2020. (3) change trends multiple significant differences removing certain important nodes, indicating redundant. research will help improve enhance improvement sustainable management restoration.

The quality of the habitats and ecosystem services are significantly impacted by ecological land fragmentation brought on human activities. However, specific driving mechanism comprehensive landscape habitat is still unclear. This study took cities Suzhou, Wuxi, Changzhou along Taihu Lake basin as its research region. spatiotemporal variations in their relationship with were explored land-use dynamic rate, transfer matrix, indices, Integrated Valuation Ecosystem Services Tradeoffs (InVEST) model, Geographically Temporally Weighted Regression (GTWR) model during 2000–2020 period. findings revealed that: (1) On whole, area rose, northern eastern areas region had greatest transformations use/land cover (LULC). (2) Within period, index showed a fluctuating growth trend, there regions large high value clustered. (3) In whole deteriorated, more concentrated degradation seen around woodland construction land. (4) Numerous factors contributed to regional temporal changes effect varied between regions. These could provide theoretical guidance for protection, improvement, restoration similar environments.

Revealing the relationship between urban spatial morphological structure (USMS) and habitat quality (HQ) is of great significance for high-quality development. In this study, central area a typical multi-mountainous city (Guiyang, China) was taken as research area. Two-dimensional (2D) three-dimensional (3D) characteristic indicators system USMS constructed. The InVEST model used to evaluate HQ in study area, pattern characteristics were analyzed. Finally, response revealed through Pearson correlation analysis curve fitting. results showed that: (1) average level low aggregation effect obvious; distribution difference high value significant; mainly distributed where large green space (UGS) remnant mountains (URMs) are located, while high-intensity construction (2)The URMs have significant impact on within city, intelligibility(I), permeability, degree, traffic attraction potential poor; buffer zone 4 km center core development, 15 rapid development (3)Among indicators, Choice(C) significantly positively correlated with HQ, Connectivity(Con), I, Average height(AVH), Otherness(O) negatively HQ.

River basins play an important role in national economic development and ecological security can be well expressed by ecosystem services (ESs) research. Due to rapid population growth climate change, it has had a significant impact on the of Yellow Basin (YRB). Although ESs have been assessed several studies, few studies used composite service index (CESI) their assessment. Thus, here, based InVEST model, bivariate spatial autocorrelation, econometric we studied YRB, with aim build CESI for evaluating overall YRB. We found that YRB from 1990 year–2020 year obvious spatiotemporal distribution law at city level grid scale, showing high characteristic southeast. The trend also showed difference regional distribution. There was positive correlation between urbanization indicators reflected urbanization, aggregation type among three similar. Furthermore, density strong spillover effect CESI, whereas land negative effect. Therefore, should pay attention transforming extensive model paying when laying out industrial structures. Additionally, is necessary control expansion built-up improve use efficiency, thereby reducing development. This study's findings serve as reference policy formulation major river worldwide.
