厚田地区单叶蔓荆的群落学特征与适应沙地的初步研究

Community Features of Vitex trifolia var. simplicifolia and Its Adaptation to Sandy Land in Houtian Area.

单叶蔓荆(Vitex trifolia var. simplicifolia Cham.)在我国主要分布于广东、广西、江苏、江西、浙江等省的沙地。在日本、印度、缅甸、泰国、越南、马来西亚、澳大利亚、新西兰也有分布。它不仅是沙地的主要固沙植物,也是药用植物。一、区域自然概况试验与调查工作在江西省南昌市厚田风沙化土地试验站进行。该区处于北纬28°25′—30′,东经115°46′50″—42′45″,位于赣江下游南昌市附近。具有高温多雨、干湿季明显的特点,是典型的中亚热带气候类型。

As preliminary investigation indicates, plants in the community belong to 12 families and 27 species. At present, the community is in an unstable state. Cultivated Vitex trifolia var. simplicifolia is still the constructive species of the community , which has many profitable properties such as developed root system, vigorous growth in covered drifting sand, strong resistance to drought and barrenness, resistance to wind erosion, etc. It is a good pionrer species for drifting sand stabilization.
