基于DPSIR模型的沂河流域水生态安全评价方法
|
摘要
准确对流域水生态安全进行定量评价,明确流域水生态安全的限制因素。对DPSIR(驱动力-压力-状态-影响-响应)模型中"状态"和"影响"指标的选取进行辨析后建立了流域水生态安全评价多层次指标体系,采用改进的群组AHP法确定各层指标权重并最终计算水生态安全指数。以沂河流域临沂段为例,对该流域2015年水生态安全状况进行评价。结果表明:流域内水生态安全状态良好区域占45.2%,一般区域占54.8%,整体处在一般区间顶部,其水生态安全指数为0.573。水生态系统结构和功能仍较稳定,但面临着流域内经济水平亟须提高的威胁以及施肥强度过大的压力,在生态投入与措施采取中,恢复水生态系统沿岸湿地是重点工作。
In order to quantitatively assess the water eco-security and determine the limiting factors of it, this method established a multi-level index system by discriminating the selection of the "state" and "impact" in the DPSIR(Drives-Pressures-State-Impact-Responses) model. After establishing the index system, the improved group AHP method was used to determine the weight of each index and water eco-security index was calculated finally. Taking the Linyi section of Yi River watershed as an example, the water eco-security in 2015 was assessed. The results show that the good regions of assessment object accounted for 45.2%, the general areas accounted for 54.8%, and the water eco-security index of the assessment object is 0.573, at the top of the general interval. The structure and function of the water ecosystem are stable, but it is facing the threat of increasing the economic level and the pressure of excessive fertilization. The restoration of wetland in water ecosystem is priority for the process of ecological investment and measures taking.
