黄河流域菏泽段农村生态环境综合评价研究

Study on the Comprehensive Evaluation of Rural Ecological Environment in Heze Section of the Yellow River Valley

为服务黄河流域生态保护,助力乡村生态发展,以黄河流域菏泽段为研究区,选取典型村庄14个,开展农村环境状况和农村生态状况监测,运用综合指数法评价农村生态环境综合状况,并对存在问题进行分析研究。结果表明:黄河流域菏泽段农村环境状况以“一般”为主,占85.7%。其中,土壤环境污染均为低风险;环境空气质量达标比例92.9%;饮用水源地水质达标比例为21.4%,未达标类型均为地下水型饮用水源地;县域地表水质达标率为26.7%。农村生态状况以“良”为主,占92.9%,少量村庄为“一般”,占7.1%,影响生态状况的主要因素为水网密度指数。农村环境质量综合状况等级均为“一般”,环境轻度污染,影响因素主要为地表水水质、土地胁迫程度和饮用水源地水质。

In order to serve the ecological protection and help rural ecological development of the Yellow River valley,14 typical villages in the Heze section of the Yellow River valley were selected as the research area to carry out the monitoring of rural environmental qualities and rural ecological qualities.The comprehensive situation of rural environmental quality was evaluated by the comprehensive index method,and the existing problems were analyzed and studied.The results showed that the local rural environmental qualities were“general”mostly,accounting for 85.7%of 14 typical villages,the environment were slightly polluted.Among them,the soil environmental pollution was low risk;the proportion of air quality up to standard was 92.9%;the proportion of drinking water sources quality up to standard was 21.4%,the unqualified types were all groundwater-type drinking water sources;the quality of surface water in county up to standard was 26.7%.The rural ecological qualities were“good”mostly,accounting for 92.9%of 14 typical villages.Only one village was“general”,accounting for 7.1%.The restrictive factor was the water network density.The comprehensive situation of all the rural environmental qualities were“general”,and the environments were lightly polluted.The main influencing factors were surface water quality,land stress and drinking water quality.
