广西位於我国南部,地势由西北向东南逐漸降低,西北部属云貴高原的一部分,中部为丘陵地。主要山脈有十万人山、大苗山、瑤山、鳳凰山、都陽山等。西江是本省的主要水系,其大支流有柳江、郁江及桂、賀江。气候具有热带及亚热帶气候的特征,气溫高,夏長,無冬季,雨量充沛,年平均在1500毫米以上,雨季集中在5—9月。如果仅从年降雨量和水文情况看,水源非常充沛,大有取之不尽用之不竭之势。但由於广西境內灰岩广佈,喀斯特非常發育,降雨多沿喀斯特裂隙及孔洞渗入地下而成地下逕流,为河流所排洩,致使本自治区广大农業区缺乏水源,造
Guangxi is located in the southern part of China. Its terrain gradually decreases from northwest to southeast. Its northwest part is part of the Yunnan-Guizhou Plateau. Its central part is a hilly land. Hundreds of thousands of main mountain mountains, big Miao Shan, Yao Mountain, Phoenix Mountain, are Yangshan. Xijiang is the province’s main water system, the major tributaries are Liujiang, Yujiang and Guangxi, Hejiang. The climate has the characteristics of tropical and subtropical climate, high temperature, summer long, no winter, abundant rainfall, the average annual in 1500 mm above, the rainy season concentrated in May-September. If only from the annual rainfall and hydrological conditions, the water is very abundant, there is great inexhaustible momentum. Due to the widespread limestones in Karst area of Guangxi, however, the karsts are very developed. Rainfall mostly flows along the karst fissures and holes into the underground and is drained by the rivers, resulting in the lack of water sources in the vast agricultural areas of this autonomous region.
