The Research Of Plant Selection And Configuration Of The Hongshui River Scenic Forest In Guangxi Dahua

The paper is focus on the research on plant species selection and plant configuration of Hongshui river scenic forest in Guangxi Dahua. The aim of this paper is to acheive the best ecological and landscape benefits in the selection of the plant which can improve the quality and landscape of vegetation of Hongshui river,can also form a stable, ecological, beautiful scenery vegetation system. In this paper, It is determined using AHP method selection the seed. And according to the coastwise geographical features to plant configuration, the acticle research results mainly has six aspect as follows:(1)This paper uses AHP to establish the plant species selection model. It proposed three level-two index system including karst-growing, coastwise-growing and appearance and ten level-three index system based on drought tolerance, rock-growing, barren tolerance, conservation of water and soil, growing power, adaptability, tree appearance, leaf appearance, flower appearance and color. Obtaining weight of the fatcor according to queationnaire survey.(2) Then these factors are quantified and scored Grading plant species in the karst scenic forest with mountain scenic forest. The plants has scored above4are Zenia insignis, Liquidambar formosana, Acacia confuse, Michelia macclurei, Lysidice rhodostegia and Dimocarpus longgana. The result shows that these plant species on growth, landscape and other aspects are relatively high, and suitable to become the backbone plant species of Hongshui river scenic forest.(3) Based on the characteristic of vision dividing Hongshui river scenic forest into three types of plant configuration area, there are visual slope plant configuration area, coastwise plant configuration area, pier plant configuration area.(4) Visual side slope plant configuration is according to the different topographic feature separating the area into three sections. There are the section from Dahua Electric Power Pants to Gongchuan township(karst), Gongchuan township to Guhe township (karst), Guhe township to Jiangnan township (mountain). The measure of plant configuration on the area is to mixed forest afforest on barren hills and wasteland, replanting and changing pure forest and low yield forest.(5) Coastwise area plant configuration is replanting the gap of plant landscape line, and separating the area into three theme parts. There are "flowers and fruits bloom all over the world","bamboo quiescence and red tree overwhelming","colorful Yao culture and aroma flow".(6) Pier area plant configuration is outstanding characteristics of the river section, where the pier in. The three piers are Dahua township travel pier, Guhe township travel pier, Jiangnan township travel pier. Each one of them reflects the Hongshui river and Yao culture.
