基于PSR模型的围填海对海洋资源影响评价方法研究

Study on Reclamation Impact on Marine Resources Based on PSR Model

利用PSR模型中压力、状态、响应相互作用的关系阐述围填海开发活动对海洋资源的影响,基于压力、状态、响应子系统确定并标准化处理了影响评价指标,根据判断矩阵分析结果赋值了指标权重,构建了围填海开发活动对海洋资源影响的评价体系,应用该评价体系进行了福建省福清湾及海坛峡海域围填海开发活动对其海洋资源的影响分析,评价结果表明福清湾及海坛峡海域围填海开发活动对其海洋资源的影响较小。

Based on and used the relationships among pressure,state and response in PSR model,this paper established a new model to analyze and evaluate the impact of reclamation on marine resources.Evaluating indicators are chosen and standardized according to the subsystem of the pressure,state and response.The values of evaluating indicators are determined by using the Matrix Analysis method.This proposed model is used to estimate the impact of reclamation on marine resources in Fuqing Bay and Haitan Straits,Fujian province.The results shows that the impact of reclamation activities in this area is not large.
