黑龙江省庆安县六合村生态农业建设与评价 Ⅱ.松嫩平原漫川漫岗农业系统能量流动和物质循环的分析

THE ECOLOGICAL AGRICULTURE CONSTRUCTION AND ASSESSMENT IN LIUHE VILLAGE OF QINGAN COUNTY,HEILONGJIANG PROVINCE(II)

本文运用系统生态学的系统分析方法,从能量流动、物质循环方面,以黑龙江省庆安县六合村为典型,对我国东北松嫩平原漫川漫岗农业系统生态农业建设前后进行分析比较研究。分析结果表明,六合村的生态农业建设为松嫩平原农业生态系统的改善,经济水平较低地区的农业发展提供了有益的经验。通过合理调整系统内的能量流及物质环循,在提高系统生产力的同时,保护农业生态环境。

The method of systematic analysis was used in this study. More attention was paid to the features of energy flow and nutrient cycle in crop and livestock subsystem before and after ecological agriculture construction was introduced in Liuhe village, Qingan county of Heilongjiang province. The results of analysis showed that the construction of ecological agriculture in Liuhe village provided a beneficial experience for the improvement of agroecosystem in Songnen plain and the development of the this lower income area. The objects of both improving agroecosystem productivity and protecting environment can be achieved at the same by the rational regulation of energy flow and nutrient cycle.
