Urban Garden Trees Expert System In Hei Longjiang Province

The test selected five representative cities as the study objects. Those cities are stand out at their virescence work. This paper investigated the living conditions, ornamental characters, ecological adaptability of the trees species in the five cities. It analyzed and summarized the applications of the garden trees, took more than 2200 photos of almost 150 kinds of trees and finished almost 6 hours' video material.
