Ecological landscape environmental optimization design for environmental protection under economical environment: Lake Wetland ecological landscape design

The purpose is to study and optimize the Lake Wetland ecological landscape design from a conservation-oriented environmental perspective. First, the conservation-oriented environmental idea is explained. Second, the Lake Wetland ecological landscape and its related theories are discussed. Consequently, an optimized Lake Wetland ecological landscape is designed by adding three-dimensional traffic elements based on its current situation. It enhances the aesthetics of Lake Wetlands and provides sustainable landscape design. In addition, numerical analysis is conducted on the water body and animal and plant richness of the proposed environmental conservation-oriented Lake Wetland ecological landscape design from 2016 to 2021. The results are as follows. The chemical oxygen demand index of the Lake Wetland water has dropped from 23.90 to 11.90 mg/L, and the ammonia nitrogen index has dropped from 1.81 to 0.80  mg/L. The chemical oxygen demand and ammonia nitrogen indexes of Lake Wetland water show a downward trend, and the total nitrogen and total phosphorus indexes have also dropped slightly. The richness of Lake Wetland animal and plant species has increased by 62.00%, with significant improvement. Apparently, the proposed Lake Wetland ecological landscape design based on the conservation-oriented environmental concept injects capital and energy into the ecosystem while retaining its primitive beauty. Compared with other studies, landscape design based on the characteristics of Wetland Ecosystems can promote economic development and optimize the ecological environment at the same time. Thus, it has urgent and practical significance for improving people's life, promoting economic development, and building a harmonious society.
