Abstract: Regard having Bishan county of Chongqing of the typical characteristic of mountain area of southwest soil and stone as the example, investigate in an all-round way through the field, one kind of square investigations and testing analysing, combine such modern science and technology as remote sensing (RS), the geographical information system (GIS), expert system (ES), etc. in the room, city Bishan little basin go on ecology is it study to monitor to repair to Chongqing. Not repairing the research of the measure with the ecology through 3 years, the result shows, the vegetation is covered with degree improves, the plant kind increases in the small basin, the quantity increases, the silt amount and flow of foot-path reduce, soil erosion lightens, it is obvious to repair the result. Meanwhile, through to influence ecology repair main factor ecology of effect repair measure, repair service life, population environmental research of capacity, the most suitable ecological repair measure in small basin is that the near naturally type ecology is repaired that we draw in Bishan, repair service life long, population environmental little capacity, repair effect to be the more obvious.
