贵州高原南端的独山县是个岩溶地貌强烈发育的山区农业县,主产水稻。由于地质构造、地貌类型的特点,加上月、季降雨量分布不稳定和砂质田土不易保水,使全县农田易受干旱威胁,既不高产又不稳产,因而兴修水利显得特别重要。该地区兴修水利要比平原和其他地区困难得多。故在措施上建议:除加强领导,增加经费的投入外,以蓄水为主,小型工程为主,蓄水、引水、提水结合。并积极开发利用地下水,扩大灌溉面积,配合其他增产措施,实现水稻的稳产高产。
Dushan County, at the southern tip of the Guizhou Plateau, is a mountainous agricultural county where karst landforms are strongly developed, with rice mainly produced. Due to the characteristics of geological structure and landform type, coupled with the unstable distribution of monthly and seasonal rainfall and the irrational water retention of sandy soil, the farmland of the entire county is susceptible to drought. Therefore, it is of great importance to build water conservancy projects. Water conservation in the area is much more difficult than in the plains and elsewhere. Therefore, measures are recommended: in addition to strengthening leadership and increasing funding for investment, the main storage, mainly small-scale projects, storage, diversion, water combined. And actively develop and use of groundwater, expand irrigation area, with other stimulation measures to achieve stable and high yield of rice.
