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