摘　　要：分析了蓄水渗膜材料的组成、工艺特性.通过内蒙古的大量试验,用统计学中方差分析的方法研究了蓄水渗膜在干旱、半干旱地区造林中的应用效果.试验采用不同土壤条件、不同栽培方案、不同时间、不同树种进行造林,调查使用蓄水渗膜和不使用蓄水渗膜对造林成活率和苗木生长量的影响.结果表明:在干旱、半干旱地区使用蓄水渗膜造林能够促进苗木生长量,提高造林成活率,干旱半干旱区常规造林成活率一般在40%-70%,使用蓄水渗膜材料造林成活率提高到85%以上,为干旱区的生态恢复提出了一套新的技术方法.The composing and the techniques of water storage and controlled-release film （WSCF） were studied in this paper. The effects of WSCF application on forestation in arid and semi-arid districts were studied according to a great deal of experiment data analyzed with ANOVA in Inner Mongolia. Under different soil condition, planting condition, planting time and tree species, the forestation survival rate and the tree growth were investigated with and without application of WSCF. The results show that the forestation survival rate and the tree growth were raised by application of WSCF in arid and semi-arid districts. Commonly in this area the forestation survival rate is 40 % to 70 % without WSCF, while it rises over 85% with WSCF. This paper presents a new technique for ecological recovery in arid districts.
