摘要

农田是绿洲的主体和主要表现形式

是绿洲社会人们重要的生产对象和生产活动空间

是绿洲的载体和基础。农田占黑河中游绿洲面积的84.2%

搞好农田防护林建设

可利用渠、路、田间地埂等边际土地做到林农复合经营

最大限度地扩大绿洲的森林覆盖率

丰富绿洲单一的农田景观

创造良好的绿洲环境。只有以农田为基础

通过林渠、林路、林田结合

发展农田防护林

才能有效提高森林覆盖率

改善黑河中游绿洲的生态环境。充分重视农田防护林的作用和意义

营造多树种混交林

加强林带更新

积极探索适合农田林网特征的节水技术是实现农田防护林进一步发展和绿洲生态环境持续改善的现实途径。

Abstract

Farmlands are the largest and most important parts of the oases in the middle reaches of the Heihe River，accounting for 84.2% of the total area of oases in the region.Shelterbelts of farmlands constitute the principal ecological conservation system of the oases.Only through better development of shelt belts can the coverage of forest in the oases be greatly enhanced，and thus the ecological environment of the oases in this region improved.The realistic pathway for further development of farmland shelt erbelts is to construct multispecies shelt erbelts，to improve regeneration of shelt erbelts and to explore water-saving technologies.
