Studies On Investigation And Screening Of Hilly Mountain Landscape Forests Understory Plants In Guangdong Province

Lack of hilly Mountain landscape forests understory plants, ecological communities is simple, the ground is bare, serious soil and water runoff, part of the mountain appeared "green desert", ecological and economic benefits decreased rapidly in Guangdong Province. Select representative hilly Mountain landscape forests plants to carry out field surveys and using document analysis, field surveys, data statistics, Analytic Hierarchy Process and other methods in Study. Establish a filter evaluation index system for hilly mountain scenic forest ecology and landscape plants chosen to provide repair method. Results are as follows in this study:(1) Survey plots Plants, arboreal plants has40families,66genera and93kinds; shrub plants has48families,90genera and109kinds; herb has41families,72genera and85kinds; climbing type liana type and22families,34genera and35kinds; plants advantage genus and local scale.(2) From the forest, slope, slope orientation, canopy four environmental factors to analyze the composition of understory plants; too extreme environmental importance values dominant understory plant species; understory plants ability to reproduce the strength of its relative abundance or relative coverage linked.(3) Constructed to adapt to the environment factor, ornamental value factors to promote the value of evaluation factor of three mountain landscape understory plants in Guangdong screening evaluation system, environmental adaptation factors include forest, slope, slope orientation, canopy density index; ornamental value factors include flower, fruit, foliage, attitude indicator; promote the value of factors including stress resistance, self-reproduction capacity utilization index; evaluation system for a total of four frames,11elements,23evaluation factor, using three or five level scoring system for each of the indicators for quantitative classification.(4) By building evaluation system, screened out understory environmental adaptation and have ornamental value, promote the value of50or so plant species, it will mountainous forest landscape ecology, landscape restoration practical guidance of great help.
