1 前言宽甸县地处辽宁东部,地质结构为石质山区。年降雨量1000—1300mm,年平均温度6.5C。全县森林面积430万亩,其中跳石塘占20%左右。森林总蓄积1752万m~3,跳石塘地区蓄积占25%左右。这些跳石多分布在宽东、宽北和宽中。其中下露河、青山沟等乡镇为最多,分别占30—35%。跳石塘,就是山上的石块成堆连片,人行其上,非跳跃则不能通行。根据跳石所处的地理环境不同和其程度不同,跳石可分为深层活跳石(又名淌石流)、浅层活跳石、死跳石三大类。浅层活跳石又分为陡
1 Foreword Kuandian County is located in eastern Liaoning, geological structure for the rocky mountain. Annual rainfall of 1000-1300mm, the annual average temperature of 6.5C. The county’s forest area of 430 mu, of which about 20% stone jump pond. The total volume of forests is 17.52 million m 3, accounting for about 25% of the total volume in the area of Tushitang. These stones are more distributed in the wide east, wide north and wide. Among them, Xialu and Qingshangou are the largest, accounting for 30-35% respectively. Jumped stone pond, that is, the mountains of rock piles contiguous, pedestrian on it, non-jumping can not pass. According to the different geographical environment where the stone is located and its degree, the stone can be divided into deep live stone (also known as drifting stone flow), shallow live stone, dead stone three categories. Shallow live stone is divided into steep
