我省人多地少,素有“八山一水一分田”之称,山地利用是我省面临的重要问题,而山地又多为花岗岩风化的赤红壤、红壤、黄壤,土层较薄,在严重的水土流失区大多数表土流失殆尽,只剩心土层或半风化的母质,有的基岩出露,生态环境恶劣。在这样的侵蚀地上种树,成为难以生长的“老头树”,给植被恢复带来了很大的困难。我省根据水土流失的程度和类型、土壤肥力等情况,结合本省的地理位置、环境条件,采取了以草先行、以草促树、草灌结合,恢复
The province has many people and less, is known as “eight mountains and one water a field,” said mountain utilization is an important issue facing our province, and mountains and more for weathered red soil, red soil, yellow soil, thin soil Most of the topsoil was lost in the serious soil erosion area, leaving only the soil layer or semi-weathered parent material with some bedrock exposed and poor ecological environment. Planting trees on such eroded earth has become a hard-to-grow “old man tree” that brings great difficulties to vegetation restoration. According to the degree and type of soil and water loss, soil fertility and other conditions in our province, taking the province’s geographical location and environmental conditions as the starting point,
