基于InVEST模型的贵州喀斯特生态系统服务功能评估研究进展

Research Progress of Guizhou Karst Ecosystem Service Function Evaluation Based on InVEST Model

生态系统服务功能评估不仅是环境保护和生态系统稳定性评估的定性、定量研究手段,同样其对人类生活的服务功能也具有重要作用。贵州是全国石漠化面积最大的省份,生态环境异常脆弱。将多种具有生态系统服务功能的模型应用到贵州省,是近年研究的一个热点。在国内外涌现出的各类生态服务评估模型中,InVEST模型的开发应用更加成熟,并且在国内生态系统服务功能评估中推广应用。基于上述原因,通过详细阐述InVEST模型的基本内容和特点、应用现状以及该模型的应用局限性和发展趋势,为该模型在贵州的应用与发展提供科学支持,并为后续的石漠化地区生态系统服务功能模型相关研究提供部分理论依据和科学指导。

Ecosystem service function evaluation is not only a qualitative and quantitative research method for environmental protection and ecosystem stability assessment, but also plays an important role in the service function of human life.Guizhou is the province with the largest area of rocky desertification in China, and its ecological environment is extremely fragile.In recent years, it is a hot topic to apply a variety of models with ecosystem services to Guizhou Province.Among all kinds of ecological service assessment models emerging at home and abroad, InVEST model is relatively mature and has been widely used in ecosystem service evaluation in China.Based on the above reasons, the basic content and characteristics of the InVEST model, the application status and the application limitations and development trends of the model were explained in detail, it provided scientific support for the application and development of the model in Guizhou, and provided part of the theoretical basis and scientific guidance for subsequent studies on the ecosystem service function model in rocky desertification areas.
