桂西北,一个石山遍布的喀斯特地貌区,大多数地域以石山为主,植被覆盖率低,地表水源稀少,也称大石山区。这里,漫山遍野都是破碎的石子、错综复杂的地下溶洞和夹杂在石缝中间的一块块沙土。河池市就位于这片大石山区。自然环境恶劣,经济水平落后,是河池的实际,但是,就是这样一个经济欠发达地区,多年来保密工作却走在了全区前列。 In the northwest of Guangxi Province, a karst topography area with a rocky hill is common. Most of the areas are mainly mountainous rocks, with low vegetation coverage and scarce surface water, also known as Dashi Mountain. Here, the mountains and plains are broken gravel, intricate underground caves and mixed with stone in the middle of a piece of sand. Hechi City is located in this piece of Dashi Shan area. Poor natural environment and backward economy are the realities of Hechi. However, it is such an economically underdeveloped area that for many years confidentiality has taken the forefront in the region.
