为了选取户外景观生态保护中的植被,分析了研究区用地现状与总体规划背景和研究区植被群落现状,给出数据来源,通过几何畸变与辐射畸变改良处理可获取较高质量的遥感图像.采用Logistic回归分析法,求出植被类型出现的概率;利用Logistic回归分析法确定对植被空间状况影响较大的因素,按照分析结果构造植物选取指标体系;通过层次分析法对户外景观生态保护中的植被进行选取,选取综合评分高的植被,间种部分观赏价值高的植被.采用所提方法对研究地区户外景观生态保护中的植被进行选取,按照选取结果对户外景观格局进行规划,发现采用所提方法选取植被后,各评价指标均在一定程度上有所改善,所提方法能够有效改善户外景观生态环境.%In order to select the vegetation in ecological protection of outdoor landscape, the present situation of land use in the study area, the background of the overall planning and the present situation of vegetation community in the study area were analyzed, and the data sources were given. High quality remote sensing images can be obtained by improving geometric distortion and radiation distortion. Logistic regression analysis was used to find out the probability of vegetation type, and Logistic regression analysis was used to determine the factors that had a great influence on the vegetation spatial status. The index system of plant selection was constructed according to the results of the analysis. The vegetation of outdoor landscape ecological protection was selected by AHP, the vegetation with high comprehensive score was selected, and the ornamental price of interspecies was selected. High value vegetation using the proposed method to select the vegetation in the ecological protection of outdoor landscape in the study area, planning the outdoor landscape pattern according to the selection results, it is found that after selecting the vegetation with the proposed method, each evaluation index is improved to a certain extent. The proposed method can effectively improve the outdoor landscape ecological environment.
