Unravelling the non-linear response of ecosystem services to urban-rural transformation in the Beijing-Tianjin-Hebei region, China

Ecological Informatics, Journal Year: 2024, Volume and Issue: 81, P. 102633 - 102633

Published: May 9, 2024

In our transforming world, ecosystem services (ESs) and biodiversity are threatened by urban sprawl with rapid urban-rural transformation (URT), jeopardizing human well-being. Understanding the effect of URT on ESs is critical, particularly in areas that have undergone urbanization. Taken Beijing-Tianjin-Hebei (BTH) region China as a typical case, this study measures from population-land-industry perspective elucidates influence each index at different stages. The process experienced decline population growth, an increase land urbanization, stability non-agriculturalization rate. particular, reveals intricate complex non-linear relationship between ESs. negatively affects grain production (GP), habitat quality (HQ), soil retention (SR), carbon sequestration (CS) has positive impact water yield (WY). Furthermore, it was found response threshold to URTIs increased over time, indicating can maintain certain degree resilience face activities. However, ensuring continued increasingly depends implementation effective management protection measures. This advances knowledge dynamics rapidly urbanizing provides valuable insights for policymakers planners guide sustainable development resource management.

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.

Multi-Scenario Simulation of Land System Change in the Guangdong–Hong Kong–Macao Greater Bay Area Based on a Cellular Automata–Markov Model

Remote Sensing, Journal Year: 2024, Volume and Issue: 16(9), P. 1512 - 1512

Published: April 25, 2024

As one of the four major bay areas in world, Guangdong–Hong Kong–Macao Greater Bay Area (GBA) is a highly integrated mega urban agglomeration and its unparalleled urbanization has induced prominent land contradictions between humans nature, which hinders sustainability become primary concern this region. In paper, we probed historical characteristics use cover change (LUCC) GBA from 2005 to 2015, forecasted future pattern for 2030, 2050, 2070, using cellular automata–Markov (CA–Markov) model, under three typical tailored scenarios, i.e., development (UD), cropland protection (CP), ecology security (ES), optimization. The findings are as follows: (1) encroachments build-up on other uses rapid accounted leading forces LUCCs past decade. Accordingly, sprawl was up 1441.73 km2 (23.47%), with cropland, forest land, water reduced by 570.77 (4.38%), 526.05 (1.76%), 429.89 (10.88%), respectively. (2) Based validated CA–Markov significant differences found patterns multiple discrepancy magnified over time driven different orientations. (3) Through comprehensive comparisons tradeoffs, ES scenario mode seems optimal next decades, optimizes balance socio-economic ecological protection. These results serve an early warning problems can be applied management policy formulation promote sustainable GBA.

Spatially Non-Stationary Relationships between Changing Environment and Water Yield Services in Watersheds of China’s Climate Transition Zones

Remote Sensing, Journal Year: 2022, Volume and Issue: 14(20), P. 5078 - 5078

Published: Oct. 11, 2022

Identifying the spatial and temporal heterogeneity of water-related ecosystem services mechanisms influencing them is essential for optimizing governance maintaining watershed sustainable development. However, complex undiscovered interplay between human activities natural factors underpins solutions to water scarcity flooding challenges faced by climate transition zone basins. This study used a multiple spatial-scale analysis to: (i) quantify variations yield service (WYs) Wei River Basin (WRB) from 2000 2020 using InVEST model remote sensing data; (ii) look at how activities, climate, topography, vegetation affect WYs sub-catchment scale geographical detector multi-scale geographically weighted regression (MGWR). The conclusive research reveals that there would be gradual increase in years 2020, as well distinct very different aggregation along climatic divide. average yearly precipitation was shown particularly linked WRB. human, climatic, plant, terrain variables has substantially higher influence than most single on differentiation WYs. Bivariate enhancement non-linear are common types factor interactions. shows significant interactions variables. Our temperature main cause semi-arid zone. In semi-humid zone, key controlling We provide new perspectives understanding management comparing drivers WYS sub-basins with conditions. Based findings, we recommend particular attention should paid restoration practices watersheds zones.

Accurate assessment of the ecosystem service value (ESV) China National Nature Reserves is great significance to protection regional ecological environment. In this paper, taking Shennongjia Forest Region as an example, based on land use data three phases in 2000, 2010 and 2020, we quantitatively evaluate spatiotemporal evolution characteristics ESV, FLUS model simulate layouts spatial distribution ESV under two scenarios 2035, carry out vulnerability analysis services.. The conclusions are follows: (1) From 2000 overall decreased by 15.48 million yuan, support services regulation always played a decisive role ESV. (2) area cultivated grassland continued shrink from resulting reduction 2.6 yuan 3.67 respectively. contribution woodland was largest, accounting for more than 95% periods. (3) Under natural development scenario, land, continue decline. decreases even more, but increases, construction compact. potential impact (PI) indexes region 2000–2010 2010–2020 were negative, while that 2020-2035Q1 −2.01, which further worsens services. However, PI index 2020-2035Q2 turns positive, 2.29, indicating goal government protect space scenario basically realized. research results can provide some reference other give consideration both environment high-quality development.
