沙生灌木开发利用现状及收获中存在的问题

Utilization of Desert Shrub and Problems in Its Harvest

我国的沙生灌木林资源丰富,主要分布在北方各省。灌木林具有巨大的生态效益,尤其是在干旱半干旱地区,其可以起到防风固沙,水土保持等作用;同时灌木林可以作为能源林、工业原料林和饲料林,具有巨大的经济效益。然而,目前沙生灌木在收获中存在一些问题,如收割效率低,没有通过性较好的配套动力装置等。

Plenty of desert shrub grows in the north of China. Shrub forest does not only have great influence on zoology, which serves for conserving soil and water and checking winds and fix drifting sand, but also have great influence on economy, which serves as energy forest, raw material forestry and forage forest. But, problems exist in shrub harvest at present, such as low mowing efficiency and no power unit with better trafficability and so on.
