Abstract
This paper through brainstorming, the Delphi method, and in-meeting & after-meeting method, screening out suitability evaluation indicators of indigenous arbors，shrubs plants for urban landscapes in Nanchang. It sets up the suitability evaluation indicator system of indigenous arbors, shrubs to urban landscapes in Nanchang. To improve bio-diversity in cities, we need to focus on indigenous plants in greening initiatives. In this study, the indigenous plants in Nanchang were investigated to analyze the current situations of indigenous plants in this region and their application in urban greening in Nanchang. The problems in using indigenous plants for greening in Nanchang City were analyzed and corresponding suggestions were made.
Highlights
The species composition of arbors and shrubs can reflect the vegetation types of a region, and the plant community of urban landscapes, which must be dominated by native plants, should be formed by simulating the natural community structure according to the plant flora of the city
2.2.2 A Study of the Suitability Evaluation System of Indigenous Arbors and Shrubs for Urban Landscapes in Nanchang With indigenous arbors and shrubs in Nanchang as the objects, the suitability evaluation indexes of indigenous arbors and shrubs for urban landscapes are stratified by expert scoring method, the weight of each evaluation index on the suitability of indigenous arbors and shrubs for urban landscapes in Nanchang is determined by the analytic hierarchy process, and the suitability evaluation index system of indigenous arbors and shrubs for urban
The suitability indexes of indigenous arbors and shrubs for urban landscapes are set as the percentage system, and are attached to different scores according to the weight of each index
Summary
The species composition of arbors and shrubs can reflect the vegetation types of a region, and the plant community of urban landscapes, which must be dominated by native plants, should be formed by simulating the natural community structure according to the plant flora of the city. The plant configuration should be dominated by native plants while supplemented by exotic plants, so as to ensure species diversity and landscape diversity, which is the basis for maintaining biodiversity. There are abundant native resources of arbors and shrubs in Nanchang, but there are still few species used in urban greening. It is necessary to put forward a method for screening excellent native arbors and shrubs so as to provide sufficient basis for the rational selection and application of native plants in urban landscaping How many kinds of them are suitable for urban ecological environment and available for urban greening? For this question, it is necessary to put forward a method for screening excellent native arbors and shrubs so as to provide sufficient basis for the rational selection and application of native plants in urban landscaping
