Abstract

Biodiversity faces heightened threats due to increasing global urbanization and land use intensity. Protecting global biodiversity through optimized protected areas is essential, yet current studies encounter challenges in measuring biodiversity, analyzing threat effects, and defining optimization pathways. We propose a framework to assess the impact of future land use changes on biodiversity in protected areas. By simulating biodiversity changes under different pathways, we evaluate the potential of protected areas in covering hotspots of natural habitats and biodiversity loss. Three scenarios (enhance protection management, optimize spatial distribution, improve global coverage) are compared to mitigate biodiversity loss. Our results found that future land use changes will lead to a decrease of 0.84 % and 0.97 % in richness and abundance. Compared to improving coverage, enhancing management and spatial optimization can also improve protection effectiveness. This study aids in identifying threats and optimizing pathways for global conservation efforts, advancing our understanding and capacity to address future conservation needs.

优化全球保护区，应对未来土地利用对生物多样性的威胁

由于全球城市化和土地利用强度的增加，生物多样性面临着日益严重的威胁。通过优化保护区来保护全球生物多样性至关重要，但目前的研究在测量生物多样性、分析威胁效应和确定优化途径方面遇到了挑战。我们提出了一个评估未来土地利用变化对保护区生物多样性影响的框架。通过模拟不同路径下的生物多样性变化，评估保护区覆盖自然栖息地热点的潜力和生物多样性的丧失。通过三种方案（加强保护管理、优化空间分布、提高全球覆盖率）对减轻生物多样性损失进行了比较。结果表明，未来土地利用变化将导致丰富度和丰度分别下降0.84 %和0.97 %。与提高覆盖率相比，加强管理和空间优化也能提高防护效果。这项研究有助于识别威胁和优化全球保护工作的途径，提高我们对未来保护需求的理解和能力。

期刊介绍： Land Use Policy is an international and interdisciplinary journal concerned with the social, economic, political, legal, physical and planning aspects of urban and rural land use. Land Use Policy examines issues in geography, agriculture, forestry, irrigation, environmental conservation, housing, urban development and transport in both developed and developing countries through major refereed articles and shorter viewpoint pieces.
