生态效益价值评估对评价水土保持工程建设效果至关重要。对全国首个水土保持生态文明城市-洛阳市洛河水土保持工程生态效益进行价值评估，在建立生态河道水土保持工程生态效益评价指标体系的基础上，通过价格替代法、影子工程法等方法模型从安全价值、景观价值、气候价值、环境恢复价值四方面进行水土保持工程生态效益评估研究。研究表明，洛河水土保持措施的实施使得年均涵养水源量增加28．06万t ，泥沙淤积量减少20．81万t ，尘埃阻滞量9107 t ，土壤侵蚀量减少209．1万t。洛河水土保持措施生态效益年均总价值为11715．9万元，其中安全效益年均价值为7145．6万元、景观效益年均价值为1966．9万元、气候效益年均价值1504．9万元、环境恢复效益年均价值为1098．5万元。研究成果可为全国河流水土保持生态建设效益评价及生态文明城市建设提供参考。
生態效益價值評估對評價水土保持工程建設效果至關重要。對全國首箇水土保持生態文明城市-洛暘市洛河水土保持工程生態效益進行價值評估，在建立生態河道水土保持工程生態效益評價指標體繫的基礎上，通過價格替代法、影子工程法等方法模型從安全價值、景觀價值、氣候價值、環境恢複價值四方麵進行水土保持工程生態效益評估研究。研究錶明，洛河水土保持措施的實施使得年均涵養水源量增加28．06萬t ，泥沙淤積量減少20．81萬t ，塵埃阻滯量9107 t ，土壤侵蝕量減少209．1萬t。洛河水土保持措施生態效益年均總價值為11715．9萬元，其中安全效益年均價值為7145．6萬元、景觀效益年均價值為1966．9萬元、氣候效益年均價值1504．9萬元、環境恢複效益年均價值為1098．5萬元。研究成果可為全國河流水土保持生態建設效益評價及生態文明城市建設提供參攷。

Valuing the ecological effects is crucial to the assessment of effect of the soil and water conservation projects .This paper firstly suggests an assessment system for the ecological effect of soil and water conservation project of the Luohe River in Luoyang City as the first national soil and water conservation eco-civilization city ,and it also calculates the value of ecological effect from 2003 to 2013 by using the alternative method ,shadow engineering price method and so on from the safety value ,the landscape value ,cli-mate value ,environment restoration .Research shows that soil and water conservation project of the Luohe River makes annual aver-age water conservation quantity increase 280 600 t ,blocking dust 9 107 t ,reducing sediment deposition erosion 2 091 000 t;The eco-logical benefits of annual total value is up to about 117 .159 million yuan ,among which contributed by security benefits ,landscape benefits ,climate benefit ,environmental recovery efficiency are 71 .456 ,19 .669 ,15 .049 ,and 10 .985 million yuan by the end of 2012 .This project makes the Luohe River areas'ecological environment improve gradually and the ecological environment improve significantly in the riverside area .The results may be a reference for the assessment of ecological effects of the erosion and torrent control works of river and construction of eco-civilization city .
