Referring to the environmental impact assessment of the rural energy ecological construction project using Asian Bank loans in Henan Province,through the monitoring of soil,kitchen air and courtyard runoff,the statistics of disease incidence to biogas farmer and non-biogas farmer,the effect of biogas construction on improving rural ecological environment were analyzed quantitatively.The results showed that the contents of available potassium,phosphorus,total nitrogen and organic matter in soil of biogas farmer were obviously higher than that for non-biogas farmer.The average content of CO,SO2,PM10 and NH3 in kitchen air of biogas farmer is lower than that for non-biogas farmer.The average content of SS,COD,TP,NH3-N in courtyard runoff of biogas farmer is lower than that for non-biogas farmer;the fly number in courtyard,the respiratory disease incidence and the gastrointestinal disease incidence were also lower for biogas farmer than that for the non-biogas farmer.

Referring to the environmental impact assessment work of the rural energy ecological construction projectusing Asain Bank loans in Henan province, the author selected different ecological patterns in proportion from nine countrysides in nine counties, and from start to end, the project spent two years to investigate more than 80 indexes which included the fanners' energy consumption, energy consumption costs, agricultural production investment and output, and so on in biogas using farmers and non-biogas using farmers. Biogas construction's promotion of the planting and breeding and the pollution gas emission-reducing were also quantitatively analysed. The analysis results showed that biogas construction greatly reduced the consumption of traditional energy, saved energy consumption costs, reduced gas emissions and significantly increased economical income of the planting and breeding. Clearly, household biogas pond construction has obvious energy efficiency, economic, environmental and social benefits.
