Current ecological value assessment models predominantly emphasize the potential of resources, neglecting crucial aspect realization processes. Analyzing resources from perspective products (EPs) is more instructive in realizing values. The key factors controlling product are value, risk, development costs, and human demand. Previous research has rarely integrated these four within zoning framework. This study proposes a suitability evaluation framework for based on “value-risk-cost-demand” perspective. First, an index system was developed, dividing EPs into agriculture (EA), industry (EI), tourism (ET), assessing them using 13 indicators. Ecological risks were modeled multi-scale patch analysis (MSPA) other models. Development costs estimated cost entropy. impact population dynamics EP demand quantified density, night-time light data, average land GDP, along with stacked buffer analysis. Next, improved TOPSIS method applied to integrate dimensions, producing comprehensive development.

Research on Human Needs and the Valorization of Supply–Need Relationships in Ecosystem Services—A Case Study of the Southwest Karst Region

Human needs alter ecosystem services (ESs), which then affect human needs. Based on the theory, in ESs are classified into four major categories of A monetization method was used to quantify service need value (ESNV), ES equivalent calculate supply (ESSV), and correlation coefficient understand relationships mutual influences among Finally, demand were compared obtain gap between for ESs. Taking Hechi City, a city with predominantly karst landscape, as an example, we found that: (1) total area high-value areas generally City increased by 10,935.15 km2, whereas low-value decreased 11,094.07 km2. (2) positive exists various demands. Spiritual material moderately significantly positively correlated, 0.54. Security correlated needs, 0.6. (3) The ESNV ESSV slightly imbalanced. Du’an requires external CNY 21.9192 million living material, while Jinchengjiang has potential export water 22.9934 ecosystems. (4) centers gravity types distributed primarily within District, only center production is northern part County. distance materials 2100.44 m, oxygen security 639.15 m. results complementary current research from perspective demand. These findings can thus provide scientific foundational information help decision makers balance region promote construction human-harmonious ecosystem.

Exploring the Dynamic Local and Tele‐Coupling Coordination Mechanism of the Ecosystem Services Supply–Demand and Its Driving Forces: Taking China's Yangtze River Economic Belt as an Example

Land Degradation and Development, Journal Year: 2025, Volume and Issue: unknown

Published: March 5, 2025

ABSTRACT Ecosystem services supply–demand (ESSD) is a key considering factor in regional ecological security. Based on the background, this study proposed dynamic local and tele‐coupling coordination degree (DLTCCD) model further analyzed its influencing factors by combining it with machine learning model. The main conclusions show that: (1) There existed great imbalance ESSD of Yangtze River Economic Belt (YREB) where upstream area was supply downstream demand area; (2) DLTCCD YREB as whole has been increasing can more objectively reflect changes coupling (CCD); (3) In future, government should prioritize dual focus demographic trends urbanization levels to foster balance YREB. This aims identify effectiveness protection projects so provide theoretical support for cross‐regional compensation policy planning area.
