In this paper,storm water conservation and the crude storm water purification in the United States of America was introduced and a storm water conserving and using system was studied and developed.

A study on water conservation function of mixed forests of Schima superba plantation;

This paper analyzes the hydrologic informations of some rive r basins in forest cover in loess hill region of Gansu Province, showing the fo rest cover in the region contributes to increase precipitation, regulates obviou sly storm-flood and annual runoff, and improves efficiently microclimate, soil and water conservation.

Water conservation functions of the four hydrology arrangements,including forest canopy layer,shrub-grass layer under canopy,litter in forest land and soil layer of the forest,in Dayao Mountain Nature Reserve in Guangxi were investigated.

By using hiberarchy analysis and comprehensive index method, the ecosystem service importance and its regional diversities in Liaoning Province were quantitatively assessed, based on the comprehensive analysis of biodiversity protection, water resources conservation, soil conservation, desertification control, and nutrients conservation.

In this paper the functions of water resources conservation were studied on three kinds of artificially recovering plantations of soil and water conservation, grass planting, arbor mixed with shrub, mixed arbors(called patternⅠ,Ⅱand Ⅲ for short respectively) and control(not improving), in seriously eroded areas of subtropical granite red soil.

The water resources and the capacity of water resource conservation in upper reaches of Dahuofang reservoir were analyzed.

The investigation on ecological environment,water resource conservation and economic status in 3 counties of Dahuofang reservoir upstream was carried out,the cost for protecting the reservoir water quality amounted to 820.
