Environmental economic principles were utilized to analyze and evaluate the environmental achievements and benefits of measures to construct ecological and clean-type small watersheds in Beijing City. The value calculation model of efficiency of land renovation

forest ecological

wetlands

grass planting

sewage and litter management and engineering measures were developed to compute the benefits of each practice. The ecology and assets values of construction measures for 3 typical small watersheds in Changping District were analyzed. The results indicated that ecological value were concentrated in the ecological restoration area in Guozhuang and Dashipo small watersheds

which covered 99.99% and 99.42% of its total ecological value

respectively

but it was centralized in ecological management area for 96.99% in Yangtaizi. Nevertheless

the assets values of all the 3 small watersheds were centralized in ecological management area

and the percentage of the total assets were 99.67%

96.16% and 91.89%

respectively.
