摘要:

以鼎湖山生物圈保护区为例,采用敏感水平、群落景观重要值、物种多样性信息指数、阴生种比例、伴人植物比例和旅游影响系数等指标,对旅游活动与植被环境的关系和景区管理水平进行了分析评价。研究表明:(1)旅游影响系数与植被环境质量评价指标之间、植被环境质量各项评价指标之间、旅游影响系数内部各因子之间均存在不同程度的相关性。敏感水平值越大,群落景观重要值、阴生种比例值越小,物种多样性信息指数、伴人植物比例、旅游影响系数值越大;旅游影响系数越大,敏感水平、物种多样性信息指数、伴人植物比例越大,群落景观重要值、阴生种比例越小;旅游影响系数与其各影响因子均呈正相关,即旅游影响系数越大,枯枝落叶层越薄、草本层盖度越小、幼苗量越小、折枝数量越多、垃圾量越大。研究结果与鼎湖山旅游发展的实践基本相符,客观上揭示了旅游活动对植被影响的规律和特点;(2)根据旅游影响系数分级标准,鼎湖山景区质量管理水平总体可定为中上水平,但个别地段存在环境隐患,有必要进一步提高管理水平。

Abstract:

The nature reserves are often faced with the contradiction between resource protection and tourist activity. It is important to study the relationship between tourist activity and vegetation environment in nature reserves. Vegetation landscapes are not only important tourism resources, but also levers of harmonizing their ecological balance. This paper analyzes the relationship between tourist activity and vegetation environment in Dinghu Mountain, and evaluates the management level in the tourism region. Six indexes are used, including the sensitive level (SL), community landscape importance value (LIV), information index of species diversity (H'), negative species proportion (NSP), proportion of plants accompanied with mankind (PPM), and tourism impact index (TII). The result shows that there are some correlations and regularity between the TII and the evaluation indexes of vegetation environment, among the evaluation indexes of the vegetation environment quality, and among the factors of tourist impact index. The larger the SL is, the larger the H', PPM and TII are, and the smaller the LIV and NSP are. However, the larger the TII is, the smaller the LIV and NSP are, and the larger the SL, H' and PPM are. The TII is positively correlated to each factor, including rubbish impact index, damaging branches impact index, woods regeneration impact index, and meadow situation index. The regularity is that the larger the TII is, the smaller the dead sticks and humus thickness, meadow coverage, sapling number are, and the larger the damaging branches number and rubbish number are. These facts indicate the regularity of tourist activity has an impact on vegetation objectively, and this accords with the fact of tourism practice in Dinghu Mountain. Based on evaluation class of TII, the management level of tourism region in Dinghu Mountain is good and middle level on the whole nature reserve, but there are some dangers in some regions which need to raise the tourism management level further. Finally, the paper puts forward some management tactics in the tourism region.
