| 摘 要： | 文章论述了科尔沁沙地植被的历史变迁和原生植被类型。提出了本地区退化生态系统植被建设的方向和目标,即根据具体地形地貌、土壤特点和残存植被特征,以改善生态环境和提高土地生产力为目标,选择生态防护和经济价值高的植物种类,组建结构不同、功能各异的人工植被体系,其结构不同于原生植被,但功能优于原生植被,形成新的高效、和谐、稳定的人工-自然生态系统。同时,对本地区植被建设的基本模式也进行了论述。

| Abstract: | Historical changes and types of original vegetation of Korqin sandy land were discussed.The directions,target and models of vegetation were put forth according to the fundamentals of restoration ecology.Taking ecological environment and productivity improvement as restoration target,artificial vegetation systems whose structure are different form and the function exceed those of original vegetation should be constructed by selecting appropriate species with highly ecological and economic performance according to different landform,soil condition and survival vegetation characteristics in order to form new,high-benefits,harmonious and stable artificial-natural ecosystem.Basic models of vegetation construction were introduced as well in this paper. |
