华蓥山国家地质公园盆景式石林的形态特征与生态成因

Morphological Characteristics and Ecological Causes of Miniascape Stone Forest in Huayingshan National Geopark

以华蓥山国家地质公园内盆景式石林为研究对象,用遮蔽指数、侧蔽指数、偏率和侧视指数4个指标对盆景式石林的特征进行描述,并分析其生态成因。结果表明,其总体特征是树冠冠幅面积大于石柱底面积,sh约为1.49;si约为0.36,石柱上部1/4部分生物的生化作用最强烈;树冠形态具有不对称性美,ti约为1.5,sl约为0.48。其形态特征与华蓥山地质基础、小气候环境植物与石柱的生长发育阶段和人为因素有关。

Based on the research object of miniascape stone forest（MSF） in Huayingshan Karst National Geopark, this paper used the method of field investigation and mapping and set up six basic parameters to describe its morphological characteristics and scale. On this basis, this paper intend- ed to describe and analyzed the ecological reason by using the shield index, side shaded index, partial rate and the side - looking index. The results in- dicated that the general characteristics were as follows：Crown breadth area was greater than the stele base area and sh was about 1.49, si was about 0.36, the biological and biochemical function of the upper 1/4 part of the pillars played a dominant role, the shape of crown had asymmetry beauty and ti was about 1.5, sl was about 0.48. The morphological characteristics of MSF were correlated with the geological basis of Huayingshan, the differ- ent germination stages of plants and pillars in the microclimate environment and artificial factors.
