Effective land use management can better maintain ecosystem services, especially in urban agglomerations. However, rational scale systems and landscape patterns to key services (ESs) highly urbanized areas remain poorly understood. Taking the Guangdong–Hong Kong–Macao Greater Bay Area (GBA) as a study area, we quantified spatio-temporal change of ESs from 2000 2020 by Integrated Valuation Environmental Services Tradeoffs (InVEST) model, simulated prior considering ES conservation priority under different multiple development scenarios 2050 adopting future simulation (FLUS) model. The main findings were follows: (1) From 2020, natural habitat, water retention carbon sequestration decreased 5.5%, 7.9%, 3.9%, respectively, while soil increased 63.7%. (2) proportion ranged 10.6% 22.6%, which mainly located mountainous region. (3) area would increase 4286.00 km2 4802.25 between GBA, with growth rate 12.05%. Under scenarios, new was distributed megacities supercities. (4) integrative scenario, habitat quality index, conservation, 0.036, 7 × 104 t, 5.11 106 t 0.93 respectively. To ESs, recommend optimizing system, making it compact at city scattered regional scale, strictly restricting conversion forestland farmland adjacent into land. These beneficial achieve high-quality sustainable via system management.

The negative impacts of human activities on the ecological corridor in the karst highly urbanized area are gradually diminishing: A case study from the karst mountain cities in Southwest China

Ecological Indicators, Год журнала: 2023, Номер 157, С. 111257 - 111257

Karst mountain cities are important population agglomerations in southwestern China, as well integral components of the significant regional economic belt - Central Guizhou Economic Belt. Ecological corridors serve crucial pathways for species migration and play a vital role integrating habitats, particularly highly fragmented ecologically vulnerable karst areas. However, it is not yet clear how human activities natural factors drive distribution ecological rapidly expanding urban areas region. In light this, based on multi-source data from 2005 to 2020, this study identified source using sensitivity analysis resistance surface model was adjusted rocky desertification factor. The Minimum Cumulative Resistance (MCR) employed extract each four time periods. Furthermore, space syntax conducted evaluate selection, integration, depth under different levels urbanization. Finally, correlation R language performed determine degree influence various driving corridors. Our findings indicate that during urbanization process, negative impact disturbance corridor urbanized has decreased. And overall development research region shown improvement over past 20 years. extreme climatic conditions have negatively affected Additionally, policy-driven measures will an By exploring spatiotemporal differentiation mechanisms two decades, our provide scientific evidence biodiversity conservation construction secure environments

Urban expansion, especially the construction of megacities, increases carbon emissions and adversely affects storage terrestrial ecosystems. However, scientific land-use management policies can increase storage. This study takes two megacities at different stages development, Beijing Tianjin, as examples to explore impact ecological conservation scenarios on both urban land use provide recommendations for planning large cities with low-carbon development goal. Furthermore, we coupled patch-generating simulation (PLUS) model integrated valuation ecosystem services tradeoffs (InVEST) simulate under a natural scenario, planned protection scenario (PEPS), policy-based restoration (PERS). From 2000 2020, had degrees expansion loss, Tianjin's dynamic degree was 0.94% higher than Beijing's, loss 183,536.19 Mg Beijing's; this trend reducing reserves will continue (NDS). Under PEPS PERS, stock increases, Tianjin is greater, an 4.51% 8.04%, respectively. most, but negative cities. Beijing's 0.40% lower Tianjin's, which deviates slightly from economic development. Megacities in rapid stage refer strictly following scope vigorously implementing effectively regional stock. mature Beijing, flexibly implement without affecting city's

Assessing and Predicting Ecosystem Services and Their Trade-Offs/Synergies Based on Land Use Change in Beijing–Tianjin–Hebei Region

Sustainability, Год журнала: 2024, Номер 16(13), С. 5609 - 5609

Exploring the spatial and temporal dynamic changes in ecosystem service functions trade-off/synergistic relationships over a long time series Beijing–Tianjin–Hebei region is of great practical significance for regional high-quality development. Taking as research object, PLUS was used to predict land use distribution 2030 under three scenarios: business usual (BAU), cropland protection scenario (CPS), ecological (EPS); InVEST model introduced assess services including water yield (WY), carbon stock (CS), habitat quality (HQ), soil conservation (SC); trade-offs/synergies among were calculated by using R GeoDa modeling. The results show following: (1) Between 1980 2020, study area witnessed varying trends WY SC, which initially decreased subsequently increased, showing an overall upward trend. In contrast, CS HQ consistently declined throughout period; HQ, CS, SC values high northwest low southeast, while value southeast northwest. (2) From SC-HQ CS-HQ, well CS-SC, characterized synergy. interactions CS-WY, SC-WY, WY-HQ demonstrated trade-offs. On whole, trade-off/synergy degree showed trend fluctuating increase. perspective scale, SC-HQ, mainly cooperative relationships. CS-WY SC-WY trade-off (3) Compared with total four types decreased, increased (EPS), respectively, increase highest scenario. terms there also differences intensity scenarios. EPS, various highest, followed CPS, lowest BAU. findings this offer theoretical insights guidance enhancing zoning Beijing–Tianjin–Hebei, providing fundamental support refining territorial configuration.

This study selects Beijing from 1980 to 2020 as the research area, utilizing high temporal resolution land use data analyze through habitat quality module of InVEST model. Unlike previous research, this employs Theil-Sen Median method and Mann-Kendall test trend changes in more accurately. has significant advantages dealing with non-linear non-normally distributed over long time series, providing a accurate reliable analysis trends. Methodologically, first collects organizes type 2020, then uses model process each year, assessing impact different types on quality. Subsequently, are used series quality, identify quantify significance changes. The results show that past 40 years, area construction significantly expanded, leading compression other land. spatial distribution shows clear difference between two sides divided by line connecting northeast southwest, west side being good east poorer. In 10 overall improved, but most areas still decreasing trend, especially western northern mountainous where declined. Based these findings, it is recommended future urban planning management should pay attention protection improvement restoration work for poor

Abstract Background In resource-based cities, long-term irrational exploitation of resources has caused severe damage to ecosystem functions, mainly manifested in the significant decline biodiversity, land degradation, water pollution, and deterioration air quality. This led a cities' sustainable development capabilities. Establishing optimizing an ecological spatial network (ESN) can promote effective transmission material energy enhance which holds fundamental importance ensuring integrity region promoting urban development. this study, by combining environment with landscape determine sources, we constructed ESN Shenmu City, mining city, based on minimum cumulative resistance (MCR) model, conducted correlation analysis between topological structure significance functions. Then, optimization strategy scheme functions was proposed. Finally, robustness used effect before after optimization. Results The results showed that high-value service areas City were predominantly located central western parts, highest value southeast. There strong degree feature vector nodes. Conclusions be optimized effectively adding stepping stone nodes new corridors. Through ESN, found more robust connectivity stability show better recovery ability function damage. research presents method for construction area provides theoretical basis realizing sustainability economy, regional development, protection City.
