绿洲景观生态规划研究--以新疆石河子垦区150团场为例

以新疆石河子１５０团场为例，利用线性规划方法，在以水定地、以林护田、维持土壤生态平衡、适地适种、草田轮作、满足社会需求、最大经济效益原则下，对该团种植业内部主要优势作物小麦、玉米、棉花、甜菜进行了优化分析，最终形成了两套优化方案。

LANDSCAPE ECOLOGICAL PLANNING OF OASIS--A Case Study on 150th Regiment of Shihezi Reclaimation Area

According to the results of cultivated land evaluation, two land use structure schemes for major crops (spring wheat, corn, cotton, beet) in 2000 are optimized and proposed by linear program method. The target function for the optimization is the highest economic benefit and the conditions are maintaining soil ecological balance, planting different crops in the suitable areas, rotation of crops and herbage and meeting the social needs. In the scheme A, the economic benefit will be bigger than that in 1995, but the planting area of beet and corn decrease in large, and the shortage of organic fertilizer will be reached up to 6890. 5 tons, so this scheme is only proposed as alternative scheme. In scheme B, the economic benefit will be reduced compared with that in 1995, but the shortage of organic fertilizer will be only 584. 7 tons and the crops will be evenly distributed in different grades of cultivated land. As a result, the scheme B is recommended to the local policy - making departments as the optimum scheme from a view of sustainable development.
