【摘要】 <正> 焉耆盆地是中部天山的一个较大的山间盆地,土地总面积13,612平方公里,其中耕地面积为115万亩,可垦荒地125万亩;博斯腾湖水面积998平方公里,湖滨沼泽地面积440平方公里。由于资源丰富,气候适宜,经过三十多年开发建设,这个盆地现已成为新疆农、牧业和渔业的重要基地之一。更多还原

【Abstract】 The comprehensive control of Yianji Basin alkaline-saline soil was studied with systems engineering method. The emphasis of control was laid on the balancing of water-salt movement in Kaidu River Basin and Bustan Lake. e.g. using different drain(?)ge and irrigation methods in various irrigation zones, reducing the underground water level, desalinating the underground water, eliminating the extrasalt on the surface and protecting the surface from excessive salt accumulation. In the Bostan Lake (the main part and the small part), balancing and accelerating the circulation of the lake water should be done so as to desalinate the water and ensure the water quality and quantity in the conrce of the Kongque River. Hence we have selected the best scheme through mathematical method and computer solution. If the methods and conditions could meet all the requirments in this scheme, the above problems will be solved within a short period and the Basin’s ecological environment will be bettered.Bv the analysis of the model, the optimal scheme was put forward with the aid of electromc computer to resolve the problems of multifactors and multiple targets in the comprehensive control of yianji Basin alkaline-saline soil and the ecological envitronment protection, and to point out at the same time the quantitative requirments of all factors involved in the development and construction of the Basin in the future and the relations between them.The use of systems engineering method in the development of agriculture in Yianji Basin has changed the one-sided, one-subject and partial method conventional used, so it is an important breakthrough in the comprehensive and multi-target planning on a large scale.更多还原
