Selection of Slope Greening Plants in Different Climate and Soil Regions of Gansu
摘要
Abstract
Slope greening is an extremely important ecological engineering measure.It can effectively prevent geological haz-ards of slope,restore ecological environment,and improve the quality of highway slope protection system.It plays a crucial role in eco-logical restoration and disaster prevention,and possesses multiple social,economic,and environmental values.Through literature re-view,field investigation,and expert consultation,the principle for universal selection of slope greening plant was established.The dis-tribution characteristic of ecological climate and soil in Gansu was systematically analyzed,and based on this analysis,a dataset of suitable slope greening plants and corresponding engineering measures for different climatic ecological zones in Gansu was developed.The investigation result indicated that according to the diverse ecological climate and soil characteristics,Gansu can be divided into 8 major climatic-ecological zones.The climatic condition,soil fertility,and constraint factors of each region show distinct features.Spe-cifically,the Southern Longnan Valley Subtropical Humid Zone is mainly characterized by brown soil and yellow soil with deep soil layer,the Northern Longnan Warm-temperate Humid Zone mainly contains cinnamon soils and leached cinnamon soils,the Southern Central Gansu Temperate Semi-humid Zone is dominated by chernozem and chestnut soil,the Northern Central Gansu Temperate Semi-arid Zone mainly contains sierozems and cinnamon-desert soils,the Northern Hexi Temperate Arid Zone mainly contains gray-brown desert soils,the Western Hexi Warm-temperate Arid Zone mainly contains irrigated gray desert soils,the Southern Hexi Alpine Semi-arid Zone mainly contains frigid calcic soils and irrigation-silted soils,and the Gannan Alpine Humid Zone mainly contains sub-alpine meadow soil and dark brown forest soil.According to the climatic and soil characteristics of each ecological zone,the physiologi-cal characteristic of suitable greening plant was determined.A scientific combination of grasses,flowers,shrubs,and tree species was proposed,and a database of adaptive plant species was established.A"climate-soil-slope gradient"three-dimensional plant selec-tion strategy was proposed.In the Southern Longnan Subtropical Yellow-brown Soil Zone with favorable climatic condition,a wide range of plant species can be used for slope greening.In the arid Western Hexi Gray-brown Desert Soil Zone with arid climate and widespread saline-alkaline soils,heat-,drought-,and salt-tolerant plants such as sea buckthorn(Hippophae rhamnoides),licorice(Glycyrrhiza uralensis),and Nitraria sphaerocarpa are recommended.In the Gannan Alpine Meadow Soil Zone with cold climate,cold-and drought-tolerant plants such as Kochia prostrata,Chinese Iris(Iris lactea var.chinensis),and Multiflower Rose(Rosa multiflora)are recommended.These findings provide a zoned and precise basis for plant selection in slope greening and ecological restoration in Gansu Province and have important practical significance for improving ecological adaptability and sustainability of greening engineer-ing.关键词
