The effects of landscape change on habitat quality in arid desert areas based on future scenarios: Tarim River Basin as a case study

Frontiers in Plant Science, Journal Year: 2022, Volume and Issue: 13

Published: Oct. 25, 2022

Human activities have caused spatiotemporal patterns of land use and cover (LULC) change. The LULC change has directly affected habitat quality (HQ) ecosystem functions. Assessing, simulating, predicting changes future trends under different scenarios LULC-influenced HQ is beneficial to planners decision-makers, helping them formulate plans in a sustainable responsible way. This study assesses simulates the Tarim River Basin (TRB) using simulation model (FLUS), Integrated Valuation Ecosystem Services Trade-offs (InVEST) model, partial least squares regression (PLSR). Since 2000, TRB experienced declining trend from 0.449 0.444, especially lower elevations (740-2000m) on sloped (<10°). decline will continue unless effective are implemented halt it. Agricultural settlement areas higher degree degradation than native habitats. shows that expansion oasis agriculture (with an annual growth rate 372.17 km2) settlements 23.50 subsequent fragmentation. In other words, HQ. Moreover, there significant negative correlation between urbanization (p<0.01), PLSR also indicate number patches (NP), area-weighted mean fractal dimension index (FRAC_AM), percentage landscape (PLAND), largest patch (LPI) were important contributors worsening Therefore, urgently needs appropriate strategies preserve its natural habitats into future, based ecological priority scenario (EPS) harmonious development (HDS), which can help maintain high-quality habitat.

Spatiotemporal Variation and Driving Factors Analysis of Habitat Quality: A Case Study in Harbin, China

Land, Journal Year: 2024, Volume and Issue: 13(1), P. 67 - 67

Published: Jan. 6, 2024

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.

Consistency and Accuracy of Four High-Resolution LULC Datasets—Indochina Peninsula Case Study

Land, Journal Year: 2022, Volume and Issue: 11(5), P. 758 - 758

Published: May 22, 2022

Open and high-temporal- spatial-resolution global land use/land cover (LULC) mapping data form the foundation of change research cross-scale management planning. However, consistency reliability use multisource LULC datasets in specific regions need to be quantitatively assessed. In this study, we selected Indochina Peninsula as area; considered four datasets: LSV10, GLC_FCS30, ESRI10, Globeland30; analyzed them from dimensions: similarity composition type, degree category confusion, spatial consistency, accuracy. The results show that: (1) descriptions different are consistent. study area is dominated by forest cropland, supplemented grassland, shrubland, other types. (2) correlation coefficient between 0.905 0.972; good; high-consistency accounts for 77.87% total. (3) overall accuracy LSV10 highest (83.25%), that GLC_FCS30 lowest (72.27%). forest, water area, built-up generally high (above 85%); bare low (below 60%). Therefore, researchers must conduct validation types before using above datasets. Our findings provide a basis selecting related on reference method assessing regions.

Linking regional sustainable development goals with ecosystem services to identify ecological security patterns

Land Degradation and Development, Journal Year: 2022, Volume and Issue: 33(18), P. 3841 - 3854

Published: July 28, 2022

Abstract Ecological security patterns (ESPs) have become an important spatial approach to alleviate the contradiction between ecological protection and economic development. The identification of sources is primary part studying ESPs, methods based on ecosystem services (ESs) been widely used. However, current method simply overlaying ESs for source has difficulty supporting different regional decision‐making needs target. Taking West Liaohe River basin in China as example, this study aims at developing four sustainable development goals (RSDGs) carbon neutrality, water security, soil biodiversity protection. Six ESs, including net production (NPP), retention (WR), purification (WP), conservation (SC), loss by wind (SL), habitat quality (HQ), from 2010 2020 were evaluated. Based mainstream research paradigm ‘source identification‐resistance surface construction‐corridor extraction‐safety pattern identification’, combined RSDGs minimum cumulative resistance (MCR) model was used identify goals. discussed, identification, optimization, construction plan comprehensive ESP discussed combination with actual situation region. found that leads neglect some areas provide key it difficult directly support decisions under objectives, while a multiobjective‐oriented helps promote their relationships. results will help improve understanding basis restoration optimization structure ‘social‐economic‐ecological’ complex system basin.

Response of ecosystem services to landscape patterns under socio-economic-natural factor zoning: A case study of Hubei Province, China

Ecological Indicators, Journal Year: 2023, Volume and Issue: 153, P. 110417 - 110417

Published: May 27, 2023

The regional landscape pattern heterogeneity and the spatiotemporal distribution of ecosystem services (ESs) are influenced by natural resources socio-economic development. Analyzing ESs impact on in different sub-regions separating natural, economic, social factors is important for development conservation. In this study, Fragstats, integrated valuation tradeoffs (InVEST) model R software were applicated to analyze response trade-offs characteristics under socio-economic-natural zoning, using a variety data Hubei Province as an example. results showed that: (1) was divided into four sub-regions: woodland protection zone (WPZ), rapid urbanization (RUZ), plain agricultural (PAZ), mountainous (MAZ). (2) water yield (WY) crop production (CP) increased 769.32 mm 5.07 × 106 t from 2000 2020, respectively, while carbon sequestration (CS) nutrient discharge (ND) decreased 6.96 2.75 107 kg, respectively. (3) There differences interactions sub-regions. WY RUZ exhibited strong trade-off relationship with remaining three ESs, ND weak synergistic two zones. (4) patterns not same dominant land types had weaker than non-dominant use WPZ RUZ. These indicate that distributions unsynchronized economic effects optimization enhances should be considered protection.
