- 摘要:
- 为建立泥岩人工边坡植生技术体系，本计划於旗山184线公路25km处试区进行第4年观察，结果表明①理想植生斜率；1：1.5及1：2区历经77，78、79、80年台风豪雨均保持稳定植生覆盖良好。②本年度调查分析182线试区结果，坡长5～7m构筑一条截水沟坡面冲蚀最小，坡长愈长，冲蚀愈烈。③泥岩理化性质的改良以施用泥炭土最为明显，泥炭土本身pH值4.7，含腐植酸35%以上，有机质90%以上，施在pH值8.6的泥岩中有显着改良土质，促进植物生长之功能。④在泥岩自然坡方面经植生带铺植进行初期观察，由於成活良好，值得继续深入探讨。本计划针对建立复层植被研究采用两种方法进行试验探讨：①一次植生法（播种法）：裸露坡面经整坡后，混合草本、野花木本种子。建立一年后，地被草花本本植物均发芽成长良好，渐具复层植被雏形。②二次植生法（植苗法）：先播种百喜草、百慕达等草类；当成活率达80%时再种植乔木、灌木及野花，栽植后木本植物的成活率达90%以上，成效良好。复层植被建立后，可使土壤表层获得完密的植物覆盖及保护，土壤中且有深浅不同的植物根系可固结土壤，对提升道路边坡稳定及泥岩植生绿化有更实际的成效。
- Abstract:
- in order to establish the effective vegetation models for mudstone areas the investigation of experimental plats set at 25 km of Chi-San highway no.184 four years ago were continuously conducted.The results of these observations were analyzed and summaried as follows: If The idea slope ratios for vegetation were 1: 15 and 1: 2.These plots kept excellent stability of vegetation even after four-year’s (1988-1991) typhoons and storms.2.The resrlts fo survoy on experimental plots at highway no.182 reveal that the slope length of about 7 m contructed with one diversion ditch resulting in the least erosion, the longer slope length the more severeerosion.3.Peat soil from indonesia improves the physic-chemical properties of the mudstone.It has PH value of 4.7, 90% organic matter and more than 35% humic acid was found to be very effective in promotion of the growth of the grasses.4.The preliminary observations made on natural slopes of mudstone using seed-belt method found that vegetation continuously.Two methods were usde to establish the multi -layer vegetation: 1.one-stage vegetatio (sowing seeds): After rough preparation of bare slopes, mixed seeds of woody and herbage plants were sown.One year after sowing, the growth of these plants was fairly good and primitive outline of multi-layer vegetation was seen.2.Two-stage vegetatio (transplanting):Seeds of bermudagrass (Cynodon dactylon (L.)pers.) and bahiagrass paspalum notatum Flilgge were sown first.After vegetation coverage reached approximately 80% woody plants and wild flowets were transplanted.Morethan 90% of transplanted woody plants were survived.Establishmest of multi -layer vegetation enable the soil protected from erosion.The use of different plant types which have different depth of root systems which can hold soil tightly.These techniques have their practical value and can enhance the stability of hillslopes closed to the highways.
