The paper presents the generalized results of long-term studies of Pinus sylvestris L. and species of the genus Populus L. in the landscaping of Blagoveshchensk. The occurrence, ecological features, categories of the state have been studied. It was determined that most often Pinus sylvestris L. is found in plantations of common use and is 26,5%, in plantations of limited use pine is more than twice as rare (10,5%), at special-purpose facilities the occurrence is 8,5%. Analysis of the occurrence of species of the genus Populus L. shows that the most common balsam poplar (83,5%) in plantations of common use, the lowest occurrence of the representatives of the genus is observed in black poplar, which is 0,5%. Recommendations are given on the use of Scotch pine and poplars in landscaping the city. The necessity of revitalization of urban plantings with the participation of old-growth poplars was determined.
Relevance of the topic. Currently, the problem of sustainable development of cities is of particular importance, where green spaces play a leading role. Tree and shrub vegetation is characterized by high ecological functions, at the same time it plays a significant role in the architectural and planning ensemble of cities and large settlements. Intensive landscaping of most cities took place in the middle of the last century, some of the existing plantings are in an oppressed overmature state, which require replacement or rejuvenating care. As a result of the reduction of areas for green construction, there is a widespread increase in the technogenic transport load. In this regard, the actual problem is the preservation of existing native species and adapted introducers in plantations, the selection of those tolerant to the conditions of a given settlement.
