摘要
在山西省隰县的小区试验表明 ,膨润土改性沥青乳剂覆盖地面后 ,可以快速产生草本植被 ,在暴雨来临前夕植被盖度较高。同时 ,对覆盖后的地面径流、土壤含水量、土层温度作了观测 ,初步认为 ,草本植被的产生是由于覆盖后增温作用。
The plot experiment made in Xixian county,Shanxi province,in1998 showed that the way of land covering with montmorillonite bitumen emulsion, can result in grass growing rapidly so as to forming dense herbaceous plant. At the same time, we determined surface runoff,soil moisture and soil horizon temperature after covering surface. The experimental results showed that the rapid growth of herbaceous vegetation is due to raise soil temperature and preserve soil water.
