小流域生态系统服务评估方法综述
A Review of Assessment Methods for Ecosystem Services in Small Watershed
摘要
Abstract
Small watershed is the basic unit of production and ecological management in mountainous and hilly areas,and its ecosystem service assessment is of great significance to understand the current situation of regional ecosystem.This paper reviews the national and international methods for ecosystem service assessment at the scale of small watershed and their research progress,and categorizes them into ecological modeling,value evaluation,and empirical statistical modeling.Then,their applicability and advantages/disadvantages are compared and analyzed from the perspectives of assessment supply and demand,applicable scope,and basic data requirements.The findings indicate that ecological modeling and value evaluation are the most used methods in small watershed ecosystem service assessments.Ecological modeling,widely applied and well-developed with a variety of models,requires high data precision,extensive model parameters,and substantial field data for validation.Value evaluation,on the other hand,can visually represent ecosystem services in monetary terms,allowing for the wide application scope,although it is difficult to capture the spatiotemporal heterogeneity of ecosystem services.The empirical statistical modeling approach establishes statistical relationship models using historical data and environmental variables.It is suitable for evaluating services such as water resource management and soil retention;however,the assessment results are significantly constrained by data quality and nonlinear relationships.The study recommends that future research should focus on the supply and demand indicator systems for ecosystem services,the improvement of assessment accuracy,and the enhancement of horizontal comparison among different assessment methods.关键词
