Abstract: Loess plateau is the birth place of Chinese agriculture,in which abundent and varied land resources are distributed.The soil stratum is rather thick and fertile, which provides an eucellent condition for growing plants and developing agriculture. In this area,irrational uses of the land and plunder managment have been Carried out for over thousands of years;the whole land has been almost cut into fragments,and the soil erosion is very serious;therefore the people’s daily life is very poor now.At the same time,the whole ecological environment becomes worse and worse,and the storm flow always brings flood catastrophe to endanger the people’s life and property in the low basin. The more extensive cultivation,the lower productivity;conversely,the lower productivity,the more extensive cultivation;the higher embankment hides the greater danger;conversely,the greater danger seeks the higher embankment. These two vicious cycles have been vigorously curried on in the Hunghe region basin.Therefore,it is an extremely urgent task to work out a long term plan for the conscientious protection,renovation and rational development and use the land resources as a whole. The only counter measure to deal with the special conditions of the loess plateau and the necessity of river dredge and development is that we have to enrich soil fertility,promote soil infiltration and strengthen soil anti-denudebility by means of rapid revegetation as an core and in addition with some necessary mechanical protection measures in order to put the total precipitation infiltrating into the ground as a strategic aim.And at the same time,all the agricultural productions are required to adjust their practices to concretely obey this strategic aim.
