围填海对潍坊北部沿海地区湿地生态系统服务功能损害影响研究

摘要

本文以潍坊北部沿海地区为例，利用市场价值法、造林成本法、影子工程法、成本替代法、成果参照法等方法，分别从湿地生态系统提供的食品生产、原料生产、氧气生产、气候调节、水质净化、旅游娱乐和知识扩展服务等7个方面，计算得出了该区域围填海造成的湿地生态系统服务功能价值损失值为1．02×104万元／年，单位面积损失为1．06万元／hm2·年。通过对湿地生态系统服务功能进行科学、全面的分析和评价，为分析围填海工程综合损益提供了科学依据，也为围填海形成后的生态恢复提供了技术参考。%Taking the northern coastal area of Weifang city in Shandong province as the study area,the value loss of wetland ecological service induced by the reclamation project is evaluated in this paper.Major ecological services of wet-land have been considered,including the food production,material production,oxygen production,climate regulation, water quality purification,tourist recreation and knowledge extension.Various evaluation methods for the ecological serv-ice value are adopted,including the market-value method,shadow project method,afforestation cost method,and dis-placement cost method.The result indicates that the total value loss of the wetland ecological services due to reclamation is 102 million Yuan /yr,and the loss per unit area is 10.6 thousand Yuan /hm2 ·yr.This work provides the basis for the comprehensive assessment of reclamation projects and technical reference for ecological restoration of wetland.
