黄冈地区的高山、丘陵占土地总面积的60％以上,绝大部分是花岗片麻岩发育的砂壤土,植被稀疏,水土流失严重。多年来,黄冈地区人民在综合治理山、水、田的过程中,高山、远山营造用材林,低山、近山、丘陵区栽植经济林,加速了荒山的绿化,有效地控制了水土流失,大大改变了山区的面貌。为了寻找保持水士、促进林木速生丰产的整地造林方法,我们从1973年开始进行了不同整地方法造林保持水土效益的研究。 The mountains and hills in Huanggang area account for more than 60% of the total land area. Most of the areas are sandy loam with granitic gneiss developed with sparse vegetation and severe water and soil loss. Over the years, the people of Huanggang Prefecture have planted timber forests in the mountains, water and fields in the process of comprehensive management of mountains, rivers and fields. The economic forests are planted in low mountains, near mountains and hilly areas, accelerating the afforestation of barren hills, effectively controlling soil erosion and greatly changing The face of the mountains. In order to find ways to keep the water taxi and promote afforestation and afforestation with fast-growing trees, we started to study the afforestation and soil and water conservation with different land preparation methods since 1973.
