Regionalization Of Guizhou Native Woody Plants Based On Local Features And Screening

In recent years,great achievements have been made in the construction of landscaping in Guizhou Province.However,the selection of landscaping plants as an important part of landscaping has a certain blindness.The Abundant local woody landscaping plants in Guizhou Province are rarely developed,the variety is lacking and some common species are frequentiy used frequently.And some common varieties are frequently used,then a city the same as the other and seriously lacked local characteristics.With the development trend of "Local Fever",people began to pursue the rural felling and desire to return to nature.In order to avoid the phenomenon of homogenization of woody garden plants in Guizhou Province,the development of provincial city(county)landscaping construction is the primary task.In this study,methods such as literature review,field survey,and other approaches were used to study the regional division of local characteristic landscape in Guizhou Province,and the recommended application strategies of woody garden plants in each division were proposed.The following research results were obtained:1)The native woody plant resources in Guizhou Province are abundant.There are 136 families,638 genera,2837 species of native woody plants in Guizhou Province,including 1380 species of arbor,902 species of shrubs,59 species of semi-shrubs,and 496 species of woody vines;There are 496 species of woody plants in Guizhou Province's cities(counties),which belong to 93 families and 245 genera.The used species account for only 17.26% of the total number of resources,including304 trees and 141 shrubs.Six species of semi-shrubs and 45 species of woody vines.2)According to the existing natural,social and human cultural divisions,combing the urban development planning of the whole province,determining the regional zoning principle of characteristic landscape in Guizhou province.with natural factors leading first-level divisions and human factors leading second-level divisions.The elements are superimposed,and through the systematic coupling ofnatural and human zoning indicators,the local characteristic landscape of Guizhou Province is divided into 23 local characteristic landscape zoning systems of three-level.3)To construct the AHP structure model system for screening and application of native woody plant gardens in Guizhou Province.The system consists of four criteria layers: C1 ornamental value,C2 ecological value,C3 adaptability,C4 application potential,and 28 index layers such as F1 plant type,F2 stem,and F3 leaves.By applying this system,a total of 803 kinds of native woody garden plant resources in Guizhou Province were selected,including 467 trees,226 shrubs,10 semi-shrubs,and100 wood vines.4)The characteristic native woody garden plants of 23 three-level districts were selected and recommended in Guizhou province.On the basis of following certain principles,based on the natural conditions of each zoning area and the status of garden plants,according to its growth types(arbor,shrub,semi-shrub,woody vine),seasonal landscape(spring,summer,autumn,winter).regional characteristics The four types of economic utilization recommend plant species with application potential,and recommend or references the city(county)tree to the cities and counties under the jurisdiction of the district city(county)flower.
