ABSTRACT 
The loess plateau is known as the birthplace of Chinese ancient culture with splendid history and 
civilization. But in recent one thousand years, because of denudation, extensive cultivation and wasteland 
rotation, the plant cover encountered destructive damage, which resulted in soil erosion and unbalance of 
ecological environment. For this reason, such a picturesque place was replaced by the one with spars 
vegetation, sandy and arid climate, as well as erosive an poor soil since 1950s, a large-scale 
comprehensive harness has been carried out, involving water and soil conservation, afforestation and 
agriculture eco-environment. The achievement is great. Five countries, located in the central part of loess 
plateau, are used as experimental areas in this paper. With the help of abundant remote sensing source 
and ground investigation information, it makes a dynamic change analysis of forest resources and 
ecological benefits. Results indicate that, water-soil conservation and afforestation take a part in 
improving agriculture eco-environment. Meanwhile, the problem on unreasonable inverse transform has 
been found in some areas.
