摘要
六安市粮食生产功能区国土资源利用中耕地、建设用地、水域用地占国土面积的94.78%,成片造林土地有限,提高绿化率只能利用"四旁"空间.本文利用通径分析法对9个"四旁"要素进行分析.结果表明,"四旁"要素决定了该区域林木绿化率的46.66%,其中田坎、村庄、乡镇所在地、农村道路和内陆滩涂5项指标是提高绿化率的关键因素.研究结果可以为乡村绿化空间选择提供数据参考.
Abstract
The farmland,construction land and water area account for 94.78% of the land resources in the grain production functional area of Lu'an City with limited land left for scale afforestation,and the"four sides"(roadside,waterside,house side and village side) space is the only space for improving the greening rate.In this paper,an analysis was made on the 9 elements of the"four sides"using path analysis method.The results showed that,in the grain production functional area,46.66% of the forest greening was determined by the"four sides"elements,in which the raised path through fields,village,township location,rural road and inland beach were the 5 key elements for improving the greening rate.The results could provide reference for rural greening space selection.
