摘要

By studying current seedling production in Honghe Hani and Yi Nationality Autonomous Prefecture, tropical and subtropical urban landscape plant production in southwest China was analyzed. Local nurseries total 6.40 km 2 , accounting for 5.1% of total constructed land area in the prefecture, and only 0.02% of the total land area in the prefecture. Application of local plant species in landscape engineering and green coverage ratio lags far behind the indexes of Chinese livable city and indexes of relieving urban heat island effect. By making proper policies and measures, seedling production can be promoted, rare and endanged wild plant species should be fully used to construct garden city, control PM2.5 and protect the living environment.
