Tourism resources are the premise and foundation of tourism development. It is of great significance to study the exploitation of tourism resources to promote the development of tourism. Jinan is famous for water, and Baimai Spring Park is a collection of springs in one place, with rich tourism resources. Coupled with the local government s attention to tourism, Baimai Spring Park, as a representative, has accumulated a rich tourism market foundation. With the support of policies, unique spring ecological and cultural resources and increasingly perfect location conditions, the high-quality development of tourism resources in Baimai Spring Park is particularly urgent. In this study, the present situation and problems of development of tourism resources in Baimai Spring Park were analyzed by questionnaire survey method, and corresponding optimization suggestions were put forward.展开更多
Since the State Council approved the development plan of the Harbin-Changchun Urban Agglomeration in 2016, the development of the Harbin-Changchun Urban Agglomeration has received extensive attention from the society....Since the State Council approved the development plan of the Harbin-Changchun Urban Agglomeration in 2016, the development of the Harbin-Changchun Urban Agglomeration has received extensive attention from the society. Starting from the perspective of "three-life space" and referring to the existing research results, this paper determines the three-life space classification system of Harbin-Changchun urban agglomeration, analyzes the problems faced by its "production-life-ecology" space in the development process, and puts forward optimization suggestions for the problems.展开更多
