针对我省水土流失现状,立足于侵蚀丘陵地,采取改造、转化、完善的技术路线,选择“林—果—药”和“果—肥—药”两种综合治理模式,探讨马尾松疏林地和荒坡地综合治理改造的可行途径。经过近四年的试验,建立和掌握了多层次、多树种、多时效集约经营的立体种植模式和技术,探索出快速改造侵蚀丘陵地、绿化荒山、控制水土流失的新途径,并提高了土地利用率,取得了显著的生态、经济和社会效益。研究的成果对于指导闽东南侵蚀丘陵地的综合治理,对提高立体种植程度及集约经营程度具有重要的现实指导意义。
According to the current situation of soil and water loss in our province, based on the eroded hilly land, we take the technological route of transformation, conversion and perfection and choose two kinds of comprehensive management modes of “forest - fruit - medicine” and “fruit - fertilizer - medicine” And feasible ways of harnessing and harnessing the comprehensive management of the barren slopes. After nearly four years of experiments, we have established and mastered the three-dimensional planting models and techniques of multi-level, multi-species and multi-age intensive management, explored new ways to quickly transform eroded hills, green barren hills, and controlled soil and water loss, and increased land Utilization rate, has made significant ecological, economic and social benefits. The results of the study have important practical guiding significance for guiding the comprehensive management of the eroded hilly land in southem Fujian in order to improve the degree of three-dimensional planting and the degree of intensive management.
