1 The economic forest is the first choice in the developing economic of the mountainous area, and have an important meaning for increasing income of the mountainous area farmers. Loess hills area of Jin-xi is suitable to the many species economic forests growing, such as the jujube, the walnut, the apricot, the persimmon, the haw and so on. At present, developing the economic forest fruit industry has become one of the important guidance in agriculture structure adjustment. Further study on the multi-cultivation pattern of ecology economic forest not only provides the scientific basis for the multi-cultivation, enhances the economic efficiency, but also is helpful to the improvement ecological environment. Therefore, according to the current situation of loess hills area: the severity of soil erosion, the fragility of ecological environment, and the lives in straitened circumstances, an idea of ecological economic forest aiming at improving ecological and economic benefit was introduced by scientific experiment, and the standard, the methods of building and management of ecological economic forest were also studied. The main results as follows:1. Analyze Shilou County’s ecological environment, the social economy, the forestry resources and the production condition, implementing the region ecology economy industrial structure pattern is the only way while carrying on many species and varieties ecology forestry development, ecology economic forest is priority to develop to realize the ecological environment government, the economy development. the implementation takes back from agriculture return the forest (the grass) under the premise of guaranteeing the grain production2. Using the multi- goals linear programming optimization model, land ratio of the agriculture, the forest, the herd is confirmed 0.22:0.45:0.33 in the Shilou county of Jin-xi area, land ratio of the timber forest, the economic forest, the conservation of water and soil forest uses is 0.18:0.37:0.45.3. According to Shilou County’s natural condition, the climate characteristic, the social economy, the forestry resources and requirement of the main economical forest types, the varieties growth to the environment, Shilou County were divided three ecology economic forests industry area. Namely the Yellow River coast ecology economic forest industry area, the middle ecology economic forest industry area and the eastern part ecology economic forest industry area.4. In loess hills area, the grade and slope are the primary factors in the jujube productive forces, the jujube output with grade and slope have the remarkable relationship.5. Loess hills area is suitable the economic forest multi-management due to climate dry, the light and hot are sufficient, the 4 kind of jujube grains multi-management pattern in the production value is in turn: jujube + rape multi-cultivation pattern > jujube + peanut multi-cultivation pattern > jujube + Day lily multi-cultivation pattern > jujube + wheat multi-cultivation pattern, the result indicate jujube + rape multi-management is the best pattern in the jujube grain intercrop pattern.6. Used the technology of the deep plowing and apply fertilizer, the organic matter of the economic forest orchard enhanced 44.86%, the entire nitrogen, the fast-acting phosphorus and the fast-acting potassium content separately enhanced 25%, 72% and 32.34%. The method improved the soil structure, enhanced the soil to preserve moisture and fertility ability.In conclusion, these research results have a practical instructing significance to the economic forest industry in loess hills area of western-shanxi.
