湖南岩石裸露面占60％以上的石灰岩山地(以下简称石山)将近有1000万亩,主要分布在湘西、湖南以及湖中的丘陵地带。按照国家以往的规定,岩裸地被列为不适宜于农林牧用地的“特角地”。在土地比较宽裕的情况下,由于不便利用未被重视,以致基本上处于荒芜状态。近年来,随着人口的增长,自然资源日趋缺乏,生态平衡遭到破坏,有的地方已开始危及到人的生存和发展,迫使人们对此引起关注。 There are nearly 10 million mu of limestone mountains (hereinafter referred to as “rock mountains”) with more than 60% of rock exposed in Hunan, mainly in the hilly areas in western Hunan, Hunan and the lake. According to the state’s previous regulations, bare rock was classified as “special angle” not suitable for agriculture, forestry, animal husbandry and land use. When the land is relatively well-off, it is basically in a state of barrenness due to the fact that inconvenience is not taken seriously. In recent years, as the population grows, natural resources become increasingly scarce, the ecological balance is destroyed, and some places have begun to endanger the survival and development of human beings, forcing people to pay attention to this.
