| Abstract: | The soil erosion over a long period of time made the agriculture environment get worse steadily in the hill area of X-L:the soil stratum beacame thin ; the fertility of soil went down ; sands and gravels increased ;the area of rock uncovered expanded ;and drought and flood took a turn for the worse. The con-termeasure of prevention for this situation is :the preservation for water and soil murtnt be ignored in economic building in the hill area ; strengthern basic building of farming land for the centre of terracing of the land on the slopes;speed up development of plant cover;and strengthern cocodtiation management |
