石河子地区泉水溢出带农业生态系统演替规律的初步研究──以石河子农学院实验农场为例

A Preliminary Research of Agricultural Ecosystem Succession Law in Spring Water Overflowing Belt of Shihezi Area ── Taking Experimental Farm of Shihezi Agricultural College as an Example

用农业生态系统演替的理论和方法，分析实验场四十多年来的变化，从认识现状入手，追溯农田生态系统的演替特征、种植业、养殖业、以及开发农业资源发展农副业生产的演替特征等。进而找出了实验场的演替规律，今后实验场生产方向应按两高一优农业目标，结合自身特点，用新的思路组织农、林、牧、副、渔生产。

Abstract We have analysed the change of more than forty years in the experimental farm with the theory and method of agricultural ecosystem succession, beginning from understanding the present, tracing back to the succession characteristic about agricultural ecosystem (emphasis on soil, weeds), planting, breeding, exploitation of agricultural resources and development of sideline production and so on. Going a step further to find the succession law of the experimental farm. Therefore from now on, we should base on the agricultural objective of high produce, high benefit and fine quality, linking its own characteristic, organizing produce of farming, forestry, animal husbandry, sideline production and fishery in a new way of the thinking.
