南雄市高标准基本农田建设与规划测量技术设计 摘 要 近代以来耕地减少的趋势都与受农耕水平影响的生态环境密切相关。南雄山地的土层本来很薄，土质容易受气候的影响而风化，雨季来时由于地面径流的作用而受到冲刷。农民耕作的强度以及不良的耕作方式、灾害的发生，加快了水土流失的速度。对山地的不良耕作习惯是长期以来造成水土流失的原因。同时南雄的水利建设受到自然生态以及社会生态的严重制约。即使南雄山区的农耕水平有了较大的提高，但是恶劣的生态环境条件制约了经济发展的水平，也制约了人们应对环境的能力，使南雄山区经济发展长期处于一个较低水平。 关键词：高标准基本农田； 规划测量； 技术设计 东华理工大学长江学院毕业设计 ABSTRACT ABSTRACT In modern times the decline in arable farming are affected by the level of influence with the ecological environment are closely related. Originally thin mountains soil of Nanxiong, the soil vulnerable to the effects of climate weathering, the rainy season due to the action of surface runoff by erosion. Peasant farming intensity and poor farming methods, disasters, accelerated soil erosion rate. Poor farming practices on the mountain is a long lead to soil erosion causes. Meanwhile Nanxiong by natural ecological water conservancy construction and social ecology severely constrained. Even mountains farming of Nanxiong has been greatly improved, the adverse environment conditions restricted the level of economic development, but also restricts the ability of people to cope with the environment, so that the long-term economic development in mountainous areas Nanxiong at a lower level. This paper analyzes the reduction of arable land mountainous of Nanxiong farmland and farming techniques required standards have evolved, as well as the relationship between the environment and ecology. Discusses the implementation of high standards of basic farmland construction and planning survey related work, to build water conservancy projects, field engineering, construction and land leveling farmland shelterbelt project construction plan and a series of facilities to provide technical support.
