在调查张家界世界地质公园土壤影响形态及影响范围的基础上,对公园游道两边不同距离土壤的硬度、含水率、容重进行了测定和分析,并通过计算各游览区土壤影响指数(SII)来评价旅游活动对公园土壤的综合影响。结果表明:游客活动对张家界世界地质公园土壤产生了较大的影响,特别是在游客相对集中的黄石寨景区和金鞭溪景区,影响十分明显;游客对土壤影响的范围主要发生在距游道两侧3米以内的范围;公园内土壤影响形态可分为单侧节型、双侧节型、单侧链型、双侧链型、十字节型和捷径链型6种类型,其中又以单侧节型和双侧节型为主;在六个景区中,距游道边缘1米、2米及3米范围内土壤的平均含水率较对照区分别低了36.6%、24.5%和2.2%;与对照区相比,距游道边缘1米、2米及3米的土壤硬度分别增加了167.9%、122.2%和15.8%,而距游道边缘1米和2米范围内的土壤容重则分别比对照区增加了26.5%和20.9%。文章对如何降低游客对土壤的影响范围及程度进行了讨论。图4表3参16。
Based on the investigation of the influence and influence of soil in Zhangjiajie World Geopark, the hardness, moisture content and bulk density of soil at different distances from the park are measured and analyzed. By calculating the soil influence index (SII) of each tourist area Evaluate the combined impact of tourism activities on the park soil. The results show that the tourists’ activities have a great influence on the soil of Zhangjiajie World Geopark, especially in Huangshizhai Scenic Area and Jinbianxi Scenic Area, where the tourists are relatively concentrated. The impact of tourists on the soil mainly occurs in the distance from the scenic spots Within 3 meters on both sides of the range; the impact of the park soil morphology can be divided into unilateral type, bilateral nodal type, unilateral chain type, bilateral chain type, cross type and shortcut chain type 6, which The average water content of soil in 1 scenic spot, 2 m and 3 m away from the edge of tour lane was 36.6% and 24.5% lower than the control area respectively 2.2%; compared with the control area, the soil hardness of 1m, 2m and 3m from the edge of the touristic increased by 167.9%, 122.2% and 15.8% respectively, while the soil in the range of 1m and 2m The bulk density increased by 26.5% and 20.9% respectively over the control area. The paper discusses how to reduce the extent and extent of tourists’ influence on soils. Figure 4 Table 3 Reference 16.
