传统的草坪建植,主要依靠人工铺栽草块或直接播种来实现,由于河道护坡坡度较大,土壤疏松且未经雨季冲刷及沉降,若采用人工栽植或直播不仅工期太长,且坡面播种难度大,播种者在坡面上难以站立,作业很困难,播种质量无法保证。播种或深或浅,草种深,出苗困难;草种浅,易被风雨侵蚀。且在施工过程中严重影响水质。从１９９８年４月至１９９９年 The traditional lawn planting, mainly rely on artificial planting grass or direct sowing to achieve, due to the larger slope of the river slope, the soil loose and without rainy season erosion and settlement, if the artificial planting or direct seeding is not only a long period of time, and the slope Seeding difficult, seeding difficult to stand on the slope, the operation is very difficult, the quality of planting can not be guaranteed. Seeding or deep or shallow, deep grass, emergence difficulties; shallow grass, easy to wind and rain erosion. And in the construction process seriously affect the water quality. From April 1998 to 1999
