This paper inquired into key questions and the strategies of sustainable animal husbandry development in the middle hilly region of loess plateau by analysed the potentialities,and put forward technical requirements to develop animal husbandry in this region.

Experimental study on ecological water use in a gully catchment of the loess plateau: effects of climate and land use change;

The water and heat condition and the ecological rehabilitation in the hilly-gully catchment of Loess Plateau;

Strategy of soil-moisture-budget-based pasture establishment in Loess Plateau;

Based on the loess hills have been classified into three sub-standing-types in West Shanxi,the paper gives the dividing of standing-types respectively,and lists the standing-type table.

The physical geography environment in west Shanxi loess hills region was comprehensively analyzed,and in view of the key project of returning farmland into forest at present,standingtype was restudied and divided into three substanding types.

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.

The funnel shaped catchment afforestation is a new forestry technique in semiarid loess hilly area.

By means of field study in Mizhi and Luochuan, Shanxi Province, the difference of form of the loess draping and the land form evolution law in the model loess hill and loess tableland area is determined.
