What are the present situation and existing problems of the ecological landscape of Orange Island Park in Changsha?

The planning idea of Juzizhou Park is to "focus on ecological culture, pay attention to the creation of characteristics, pay attention to the development of integrity and publicity, and build Juzizhou into an ecological oasis". Juzizhou Park takes "ecology, culture, tourism and leisure" as the planning theme and ecology as the planning focus. After the environmental renovation, the land area of Juzizhou Park reached 9 1.64hm2, and the greening rate of the whole park reached 86%. Since the opening of the park, the scenic area has rich vegetation, clear water, good integration of soft and hard landscapes, beautiful and pleasant environment and outstanding ecological effects [3]. In short, a large number of tourists come to visit and watch every day. This paper expounds the present situation of ecological landscape of Orange Island Park from the aspects of plant landscape, water landscape and revetment landscape. The existing problems are: 1. The ecological benefits of large lawns are relatively poor. There is a large landscape lawn at the entrance of Orange Island Park. Since scenic spots are open to the public free of charge, the mainland receives a large number of tourists every day, especially on holidays. More and more tourists have caused great difficulties to the maintenance of landscape lawns. Lawn is often withered by tourists trampling too much, which seriously affects the ornamental effect of lawn and has relatively weak ecological benefits. At present, Orange Island adopts artificial supervision, which prohibits tourists from stepping on and crossing the lawn, making the lawn purely ornamental. This method can't solve the problem fundamentally. The author thinks that reducing the lawn area appropriately and replanting ornamental plants at the edge of the lawn may alleviate the problem to some extent. 2. The pests on the mainland didn't take corresponding measures. The insect pests in Orange Island are serious, and many ornamental plants have insect pests. For example, the diameter of the Chinese rose planted on the edge of the lawn, although the effect is very good from a distance, many Chinese rose flowers and leaves have the phenomenon of missing engravings and holes. In the author's observation for several months, the pest phenomenon in Orange Island has not been controlled. This not only affects the growth of plants, but also affects the mood of viewers, which should be paid attention to and dealt with.
