1980年7～11月,国家农委组织一批技术人员,协助兴国县进行了水土流失、自然资源及社会经济状况的综合考察,编制了综合区划图集和水土保持综合区划报告,现将报告摘要如下: 一、自然及经济概况 (一)自然概况 兴国县总面积3215平方公里,属于亚热带南部,东、西、北三面地势高峻,群山重叠,并逐渐向中、南方向降低、构成以县城为中心的地势起伏和缓的盆地。山川形势和山脉走向,在东北部以北东,北北东为主,西部以北西到北东弧形分布,中北部以南北向为主。流水侵蚀及剥蚀、夷平作用强烈,区内近代处于相对稳定阶段,河流向源侵蚀作用强烈,支流上游水流急湍多峡谷,中下游河道开阔曲流发育,堆积作用明显,形成大片沙滩。根据地貌成因和形态可分为以下几个基本类型:
From July to November 1980, a number of technicians were organized by the State Commission of Agricultural Affairs to assist Xingguo County in carrying out a comprehensive investigation of soil and water loss, natural resources and socio-economic conditions. A comprehensive zoning atlases and a comprehensive zonation report on soil and water conservation were prepared. Now, The summary is as follows: I. Natural and Economic Overview (A) of the natural profile Xingguo County, a total area of 3215 square kilometers, belonging to the southern subtropics, east, west and north three terrain is high, the mountains overlap, and gradually reduce to the south, The center of the county is undulating basin. The mountainous and mountainous conditions are mainly northeast and north-north east in the northeast and north-northwest in the west and north-north in the north-central. Water erosion and denudation, razing effect is strong, the region in a relatively stable stage of modern times, the river erosion to the role of a strong tributary of the upstream tributaries of the rapid turbulent multiple valleys, midstream and downstream rivers open meandering development, accumulation of significant role in the formation of large beaches. According to the formation and causes of morphology can be divided into the following basic types:
