摘要:为改善天水市麦积区水土流失问题,本文从水利的可持续发展、农业的可持续发展以及生态的可持续发展方向入手,分析了麦积区水土保持现状及治理新方向,通过建设可持续发展的水利、农业、生态来保护麦积区水土资源,以植树造林,种植牧草,发展畜牧业为手段,发展水土保持型生态环境和生态农业,建设基本农田,从而带动麦积区经济发展。
Abstract: In order to improve the soil erosion in Maiji Area of Tianshui City, this paper analyzes the status quo of water conservation and the new direction of water conservancy in Maiji Area, from the sustainable development of water conservancy, sustainable development of agriculture and sustainable development of ecology. By sustainable development of water conservancy, agriculture, ecology to protect the Maiji Area of water and soil resources to afforestation, planting grass, to develop the animal husbandry as a means to develop soil and water conservation ecological environment and ecological agriculture, the construction of basic farmland, thus driving the economy development of Maiji Area.

1 麦积区概况
天水市麦积区位于甘肃省天水市的东南部,东接宝鸡市,西靠甘谷县,南邻两当县、徽县,北连清水县、秦安县。麦积区地处东经105°25′~106°43′,北纬34°06′~34°48′之间,东西长123km2,南北最宽处50km2,最窄处不足5km2,海拔在1000~2100m之间,区内山脉较多,地势西北高,东南低。东部和南部的地层褶皱隆起,形成山地地貌。北部为黄土丘陵地貌。中部小部分地区因受纬向构造带的断裂,形成渭河地堑,经第四纪河流分育和侵蚀堆积,形成渭河河谷地貌。全区总面积3480km2,其中水土流失面积已达1512km2,占全区总面积的43.45%,致使区内土地肥力大大降低,极度贫瘠,耕地面积大幅减少,植被破坏程度严重,农业的基础条件恶化,干旱随之加剧。这些都成为制约麦积区社会全面进步、经济发展以及生产水平提高的障碍性因素。因此,麦积区全区治理水土流失,保护水土资源,积极有效开展水土保持工作,已是刻不容缓。
