湖南丘陵区耕地道路系统优化模式研究(附规划图)(9700字)
—以浏阳市古港镇港星村为例
摘 要:湖南丘陵区的坡耕地长期以来存在着田间道路荒废,道路过陡、弯道多、转弯幅度大,田间道路不断侵蚀耕地等问题。本文以湖南省浏阳市古港镇港星村为例进行耕地道路系统优化模式的案例研究。主要取得了以下研究成果:根据地形、地面坡度、土层厚度及土壤情况,将规划区改造为田成方、路成网、沟渠贯通的农业园;在充分利用区内原有道路的基础上,新增部分田间道与生产路,使区内路网互通,方便农民及各种小型机械就近下田作业;合理规划格田,以改善农业生产条件。通过耕地道路系统的优化,能大大改善项目区的交通条件,更加有利于项目区农民的生产与生活,提高了土地利用率和农业生产效率。

Study On Road System In Cultivated Land In Hunan
—Taking The Gangxin Village Of Gugang Town Liuyang City For Example
Abstract:Hunan has long sloping hill areas there abandoned the field road, road over steep, curved and more, turn amplitude, the steady erosion of arable land field road and other issues. In this paper, Gugang Town, Liuyang City, Hunan Province, Gangxin village as an example the road system optimization model case study. Main achieved the following results: According to the topography, land slope, soil depth and soil conditions, will be transformed into fields prescription planning area, the road into a network of canals through the Agricultural Park; to take full advantage of the region on the basis of existing roads, new Field Road and the production by some way, so that local exchange network to facilitate the farmers and various small machines operating near Shimoda; rational planning cell field, in order to improve conditions for agricultural production, increase agricultural productivity. Road system through the optimization of land, has greatly improved traffic conditions in the project area, project area farmers more conducive to the production and life, improve the efficiency of land utilization and agricultural production.
