摘要:提高滨海湿地保护利用管理水平对于保护滨海湿地，维持海岸带生态系统平衡具有非常重要的意义。选择沿海辽宁、河北、天津等10省市作为研究区域，在综合考虑经济、社会和生态三方面影响因素的基础上，构建评价滨海湿地保护利用管理效率指标体系，运用层次分析法（AHP，Analytic Hierarchy Process）对指标体系进行优化处理，代入到非导向超效率SBM（Slack-Based Measurement）模型中计算得到2006-2015年各省市滨海湿地保护利用管理效率值。结果表明：2006-2015年沿海10省市滨海湿地保护利用管理效率评价值总体上呈现"两头高，中间低"的变化情况；在100个决策单元中，达到有效的决策单元占71%，无效决策单元占29%；滨海湿地保护面积不足和资金投入冗余是无效决策单元效率值低下的主要原因。在效率结果分析的基础上提出滨海湿地保护利用的管理建议。



Abstract:The coastal wetland of China is facing the problems of continuing reduction of acreage, degrading ecological functions and depletion of coastal fishery resources. Consequently, natural coastal wetland area was substantially lost due to land conversion, petroleum production, coastal aquaculture, and salt farms. However, with the implementation of the National Wetland Conservation Program (2002-2030), the increase investments of the central and local governments, have not done that much to mitigate the existing problems. This paper aims to measure 10 coastal provincial management of coastal wetland conservation and utilization from 2006 to 2015. We collected land use data, the number of staffs, capital investment, coastal wetland conservation areas, coastal wetland production and sewage treatment rate. First, we constructed an evaluation indicator system for coastal wetland protection and utilization management. Second, we used Analytic Hierarchy Process (AHP) method to optimize indicator system to acquire the values of all input and output indicators. Finally, we used Super Efficiency-Slack Based Measurement of Data Envelopment Analysis (Super SBM-DEA) model to calculate the management efficiency of the 10 coastal provinces. The results showed that the effective Decision-Making Units (DMUs) accounted for 71% and the invalid DMUs accounted for 29%. Most effective DMUs were seen in 2006, 2007, 2008, 2014 and 2015. Fujian, Guangdong, Hainan, and Jiangsu contained nearly half of the inefficient DMUs. While Shandong, Hebei and Zhejiang showed the most efficient DMUs scoring nearly 90%. Out of six indicators, two main indicators contributed to a reduction efficiency which are lack of protected areas of coastal wetland and the under-utilization of capital investment. Our results will lay a scientific foundation to improve the efficient management of coastal wetland.
