    红壤侵蚀区水土保持植物配置模式

    Disposition pattern of soil and water conservation plant in red soil erosion area

    • 摘要: 为探索中国南方红壤侵蚀严重区水土流失快速治理的方法和途径,在江西省的修水、宁都、石城等县花岗岩发育的红壤侵蚀区,对16种水土保持植物配置模式的植物生长状况、蓄水保土效益、改土增肥效益、经济效益4方面进行观测,通过建立评价模型,对不同人工植物群落配置模式的水土保持效益进行综合定量评价。结果表明:修水试验区马尾松+木荷+胡枝子+黄栀子、马尾松+木荷+泡桐+胡枝子,宁都试验区马尾松+木荷+胡枝子,石城试验区湿地松+枫香+胡枝子+硬骨草、湿地松+胡枝子+硬骨草和湿地松+胡枝子+百喜草配置模式各种效益表现优良,可以在同类地区大力推广。

       

      Abstract: In order to find the approach of fast controlling soil erosion in the red soil erosion area of southern China,the observation on status of vegetation growth and benefits of 16 patterns of plant disposition in red soil area are carried out which include benefits of soil and water conservation,melioration and economy.Results showed that pinus massoniana+Schima superba+Lespedeza bicolor Turcz.+Gardenia jasminoides Ellis,pinus massoniana+Schima superba+paulownia+Lespedeza bicolor Turcz.in Xiou-shui area,pinus massoniana+Schima superba+Lespedeza bicolor Turcz in Ning-du area,Pinus elliottii+Liquidambar formosana Hance+lespedeza bicolor Turcz.+Panicum repens L.,Pinus elliottii.+Lespedeza bicolor Turcz.+Panicum repens L.,Pinus elliottii.+Lespedeza bicolor Turcz.+Paspalum natatum etc in Shi-cheng are good beneficial.Those patterns should be applicated to similar regions.
