护岸堤林建设是建设是长江中上游防护林体系建设林种空间布局与配置不可缺少的有机组成部分,具沿江而布及成连续林带的特点。其发展的土地潜力取决于岸堤线长度、林带建设宽度和建设地带内的土地利用现状结构等三个因素。研究结果表明:长江中上游研究江段护岸堤林发展土地数量潜力规模为25123.4~41938.9hm2,其中需造林绿化的宜林荒地地(第一类潜力)为8214.5~13757.3hm2,需改造更新的疏灌林地和需加强抚育的未成林造林地(第二潜力)为5409.3~9015.5hm2,需退耕还林的耕地(第三类潜力)为11499.6~19166.1hm2。
Embankment embankment construction is the construction of the middle and upper reaches of the Yangtze River shelterbelts forest spatial layout and configuration of an integral part of the organic, with the distribution of the continuous and along the river into a belt characteristics. The potential of land for development depends on three factors: the length of embankment line, the width of forest belt and the current status of land use in the construction zone. The results show that the potential scale of embankment embankment development in the middle and upper reaches of the Yangtze River is 25123.4 ~ 41938.9hm2, of which the suitable land for afforestation (first type potential) is 8214.5 ~ 13757.3hm2 , The need to transform and rehabilitate dwarf forest and need to strengthen tending afforestation (second potential) of 5409.3 ~ 9015.5hm2, need to retreat farmland to forest (third potential) is 11499.6 ~ 19166. 1hm2.
