中文摘要	[目的]研究高陡边坡区存在植被退化、植被建植困难、保水性能差、水土流失等问题,为半干旱区高陡边坡生态修复提供新的思路和借鉴作用。[方法]提出了3种建植技术锚索框架植生袋平铺法建植技术(A区)、锚索框架植生袋梯田法建植技术(B区)和锚索框架梯田法(C区),以解决该区建植中存在的问题,维护工程建设和运营安全。[结果]①A区植被覆盖度最高(85%),且植物种类和株数最多;B区和C区盖度分别为60%和12%。②020cm土层间,土壤含水量表现为:B区(7.72%)>A区(7.20%)> C区(4.03%);02cm土层间土壤含水率:A区(5.82%)>B区(3.95%)>C区(2.88%);210cm和1020cm间:B区>A区>C区。③020cm土层间土壤容重表现为:A区(1.18g/cm~3)C区(1.19g/cm~3)>A区(1.15g/cm~3),且容重均处于适宜状态;1020cm土层间:A区(1.21g/cm~3)
英文摘要	[Objective]The problems of vegetation degradation,difficulty in vegetation construction,poor water retention,and soil erosion in high and steep slope areas was studied to provide new ideas and reference for ecological restoration of high and steep slopes in semiarid regions.[Methods]Three types of vegetation construction technique were considered:anchorage frame planting bag tiling method (plot A),anchorage frame planting bag terrace method(plot B),and anchor cable frame terrace method(plot C).These three techniques were used to solve the problems of vegetation construction in the region and maintain the safety of construction and operation.[Results]① The maximum vegetation coverage was 85%in plot A,and the plant species and number were highest.The coverages of plot B and plot C were 60%and 12%,respectively. ② The soil moisture content of soil layers between 0and 20cm was as follows:B(7.72%)> A (7.20%) > C (4.03%).At 02cm layer,the soil moisture content followed A (5.82%)> B (3.95%)> C (2.88%),and at 210cm and 1020cm layers,it was B> A >C.③ The soil bulk density of soil layers at 020cm was A(1.18g/cm~3)C(1.19g/cm~3)> A(1.15g/cm~3),and the bulk density was in a suitable state.At 1020cm,it was A (1.21g/cm~3)< B(1.25g/cm~3)< C(1.31g/cm~3),and the C area was in a tight state.④ The order of soil erosion modulus was A (3 078t/km~2·a)
