With respect to protective forests such as those for water supply conservation, water and soil conservation, windbreak and sand& fixation, felling shall only be permitted for tending and regeneration of forests.

Experiments of intercropping crops and forest trees carried out in artificial white elm forest show that different intercorpping types and numbers of years have obvious effects on the growing of wind-breaking and dune-fixing forests;

在白榆人工林内进行的农林间作试验表明：不同的间作类型和不同的间作年限，均对防风固沙林的生长有显著影响；

The effects of the sandbreak forest system in Yulin sandy area on the sandbreak, soil improvement and natural vegetation recovery were studied by investigating their configuring structure and species.

通过对陕北榆林风沙区防风固沙林体系的配置结构、树种组成、防风固沙效益、改良土壤的作用以及对天然植被的影响等的调查、观测和分析，结果表明：其配置结构较为合理。

Binhai sandy waste, some of farmland flooded and villages, and cause serious harm planting sand-fixing forest received some success.

滨海沙荒有的淹没农田和村庄，危害严重，种植防风固沙林带收到一定效果。
