    Abstract:

    Supported by the RegionManager software, the land utilization condition before and after compre-hensive management in the Jianshanhe small watershed is investigated, and its land quality is assessed using the comprehensive index method and AHP. The result from the investigation shows that the areas of forest-land, shrub land,fruit land, and terrace land are increased by 423.5, 299.9, 17.6 and 32.0 hm2, respective-ly. The areas of new open forestland,sloping farmland, and bare land are decreased by 487.4, 164.3 and 164.5 hm2, respectively. Conservation land and economic forest land are two new land types. Irrigated land, water-land,unutilized land and difficultly utilized land are balanced.The result of assessment indicates that the 3rd and 4th grade lands account for 67.20% of the whole area before restoration, while the 2nd and 3rd grade lands account for 71.37% of the whole area after comprehensive management. In one word, the land quality rises one grade, and gets a remarkable effect after management.
