Study of the Methodology of Evaluating Paddy Ecosystem's Multifunction
摘要
Abstract
Since the multifunction of paddy ecosystem has been recognized, its evaluation has become a new hot spot, but the methodology system has not formed yet. Based on the existing literature, paddy ecosystem services were divided into four categories: supply, regulation, support and cultural services, and were refined into 11 indicators for evaluation. The value of social security and domestic waste disposal shouldn't be ignored. At the same time, negative values were integrated into the methodology system of paddy ecosystem valuation, namely evaluation of the negative external costs caused by agricultural chemical pollution, water consumption, greenhouse gases emission and land reclamation from lakes. The paper was aimed to propose the most update and comprehensive evaluation methodology of paddy ecosystem, to improve the valuation results, and to enhance public awareness of the value of multifunctional paddy ecosystem.关键词
