Abstract: The rapid development of urbanization reduced the proportion of urban ecological land use, resulting in the increasingly contradiction between urban ecological environment management and ecological land use demand. Improving ecological land function could be an important measure to alleviate the contradiction between ecological land use and ecological environment control needs. Taking the urban landscape forest establishment in Longquanyi District of Chengdu as an example, the research was carried out on the establishment technology of urban landscape forest in land resource conservation type, from the aspects of urban landscape forest establishment model, forest management technology, forest community structure and forest landscape characteristics.①In the case of peach trees, for the abandoned orchard with the characteristics of "green community with small amount, lack of color in summer and autumn, less green in winter", the three-dimensional green quantity of the community increased by 21.7 times, after the transformation of tree species, which also modified the different ornamental characteristics of the Koelreuteria paniculata,Pistacia chinensis Bunge and Cinnamomum camphora (L.) Presl. in the stand, and realized the "color increase in summer and autumn " and "green supplement in winter". ② For the pure eucalyptus forest with no seasonal landscape change and low forest landscape quality, the flowering and foliage trees were supplemented in the forest window, and the ornamental herbs were arranged under the forest, which enriched the color of the forest and enhanced the quality of the forest landscape. ③ For the pure Magnolia denudata forest with only one season viewing, the forest viewing time was extended from spring to winter by introducing trees such as Lagerstroemia indica, Hibiscus mutabilis and Bougainvillea glabra. Mainly based on native tree species, using multi-level configuration mode of arbor and shrub, using appropriate management and protection measures, a plantation community of land-resource-saving urban landscape forest could be establishment with high ecological service, high landscape quality and long viewing period.
