岩质边坡上植物地境结构研究
|
摘要
植物地境决定着植物的存活与生长。高陡岩质边坡复绿的关键在于构建能够提供植物的地境需求。本研究对宜阳县锦屏山岩质边坡上植物的地境结构进行研究,为该边坡复绿提供技术支撑。得出结论:(1)植被地境深度以40cm为界,受底层岩石胁迫其根群层片发育不完整;(2)边坡及岩缝中土壤肥力略差于国家九类土标准,但可以满足植被生长的基本需要;(3)土壤含水量能够保证植物基本生长需求,在目前气候条件下、在没有人工养护的前提下植被可具有自组织功能持续生长。
Plant below-ground habitat determines the survival and growth of plants. The key to recovering green of high-steep rock slope is to construct the demand of provide plants below-ground habitat. This study studied the below-ground habitat structure of plants on the rock slope of Jinping Mountain in Yiyang County, and provided technical support for recovering green of the slope. The following conclusions are reached: the depth of plant below-ground habitat is bounded by 40 cm, and the roots are not fully developed under the stress of bottom rock; the soil fertility in slopes and rock joints is slightly worse than the national nine soil standards, but it can meet the basic needs of plants growth;the soil water content can ensure the basic growth requirements of the plants. Under the current climatic conditions, the plants can have self-organizing function and continue to grow without artificial conservation.
