中文摘要 | 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。 |
英文摘要 | For the establi shment of protective forest system in the region of mid-upper Yangtze river, protecting planting along river bank or valley slope is an important component. The potentiality for the development of protectivebelt depends upon the land that can be made use of . In this paper, the main factors relative to potential land for forestation are analyzed, at the same time, the total length of river side suitable for forestation, the nessesary width of the woods belt to realizeits function, and the utilization condition of the existing land are explored; three formulae for width computation of the riparian woods and the rate of varied types of used land to whole area are proposed. The result shows that the total potential land in the valley of mid-upper Yangtze river and its main tributaries is from 25100 hm2 to 41900 hm2 approximately , of which the area of wasteland suitable for forestation is from 8200 hm2 to 13700 hm2 , the sparse woods and shrubareas are from 5400 hm2 to 9000 hm2 , the area of cultivated land (to be returned to forest land) is from 11500 hm2 to 19200 hm2 . |
