Cuscuta is an annual parasitic herb in Convolvulaceae family Cuscuta. This project investigated the spread of cuscuta in 12 towns and 1 street that have 71 plots of the Chengdu, Tianfu New District by selecting a certain area of strip and circular plots, and proved the distribution pattern and growth situation of cuscuta in this area. The results showed that: (1) Cuscuta in this area 1 genus 2 species, respectively for Cuscuta chinensis and Cuscuta japonica, of which Cuscuta chinensis accounted for 80%, the Cuscuta japonica accounted for 20%; (2) The two cuscuta species parasitized 40 plants of 30 families, 37 genera in 14 sites, and three host plants of Magnoliaceae were found for the first time in this survey. (3) The parasitism of the cuscuta showed the following pattern: plot afforestation > road afforestation > park afforestation > unmanaged wasteland, and the host plant species of plot afforestation was the largest, and the infection of road afforestation was the most serious. (4) Cuscuta for the parasitic environment sel-ection tends to high light intensity, air humidity about 80%, high plant density, more plant species conditions, in the selection of the parasitic site, is more likely to appear in the middle and upper region of the host plant. The results of this project can provide a theoretical reference for the studyof local landscape protection, and provide a theoretical basis for the development of local greening and tree cultivation.
