华蓥山长高了! 整个华蓥山体长高10多米,仅仅是10多年的事,应该说这是一个奇迹。 说是奇迹,不能没有对比。 林地面积由50年代的42万亩减少到1981年的30万亩。其中成林仅有15万亩。立木蓄积量由50年代的272万立方米减少到1981年的10万立方米。那年月的“以粮为纲”、“大炼钢铁”,使森林植被的大量毁坏,山地裸露面积增加,导致了水源逐渐枯竭,水土大量流失,空气污染严重,木材愈来愈短缺。 四川省华蓥市溪口镇1981年时,有的地方河床竟比耕地高出两米。水土流失面积达20万亩,占总土地面积的32％。
Huaying Mountain is tall! The entire Huaying Mountain is more than 10 meters long, only a matter of more than 10 years. It should be said that this is a miracle. That is a miracle, can not be no contrast. The area of forestland decreased from 420,000 mu in 1950s to 300,000 mu in 1981. Among them, only 150,000 mu of forest. The volume of stumpage was reduced from 2.72 million cubic meters in the 1950s to 100,000 cubic meters in 1981. In that years of “taking grain as the key link” and “making steel”, a great deal of destruction of forest vegetation and an increase in the exposed area of mountainous areas led to the gradual depletion of water resources, the drastic loss of water and soil, the serious air pollution and the shortage of timber. In 1981, Xikou Town, Huatuo City, Sichuan Province, in some places, the riverbed was actually two meters above the arable land. Soil erosion area of 200000 acres, accounting for 32% of the total land area.
