Abstract:: According to the present situations of severe soil and water loss, heavy soil degradation and low soil fertility in Jinlei small watershed of arid-hot valleys, we developed an application research on the comprehensive control of the Jinlei small watershed by the use of the tropical forage and shrub’s functions in livestock to feed, soil improvement and soil and water conservation. And the research results showed as follows:①Intercropping of Dimocarpus longgana Lour. and Stylosanthes guianensis improved soil quality significantly. With plant aged, soil organic matter and available N, P and K increased accordingly year by year. ②To plant Gliricidia sepium (Jacq.) Steud.as hedgerows on arable land could prevent soil erosion to some extent and increase soil quality. The cross slope planting could decrease 76.02% of soil and water loss and the erosion modulus decreased 12 986.8 t/(km²·a), It was good for improve soil quality to plough into fresh leaf of Gliricidia sepium (Jacq.);③To feed rabbit with several mixed fresh forage made economic benefits in courtyard economy. Study on the effects and economic benefits of feeding New Zealand meat rabbits with the Cichorium Inlybus showed that its dainty characteristic was the best choice and Cichorium Inlybus also had good feeding effect, all of which meant that Cichorium Inlybus was suitable to expand its planting area to develop meat rabbit feeding.
