2.1 技术简介
技术定义:
an allignment of stone along the contour line which stabilzes with grass species
2.2 技术的详细说明
说明:
Description: construction of stone bunds along the contour to reduce soil erosion, conserve moisture, decrease slope length, and to decrease down stream siltation. It is integrated with biological SWC measures and maintenance is made where ever necessary. The technique enhances the growth of natural grasses and improves the micro climate.
