In the afternoon of April 23, General Secretary Xi Jinping hosted a symposium on promoting the development of the western region in a new era in Chongqing and delivered an important speech, stressing that we should adhere to high-level protection to support high-quality development and build a solid national ecological security barrier. High quality development is the primary task of comprehensively building a socialist modernized country, and high-level protection is an important support for high-quality development. As the source of many major rivers such as the Yangtze River and Yellow River, and a strategic continuation of important national resources, the western region plays a significant role in the overall reform, development, and stability of the country, and holds an important strategic position in maintaining national ecological security, water security, energy and resource security, national defense and border security. Strengthening ecological protection and construction in the western region is of great significance for ensuring China's national ecological security and achieving sustainable development. General Secretary Xi Jinping's important statement on the overall promotion of high-quality development and high-level protection has provided fundamental guidance for the western region to further form a new pattern of large-scale protection, opening-up and high-quality development, and to strive to write a new chapter in the development of the western region in Chinese path to modernization. In the implementation of the Western Development Strategy in the new era, it is necessary to properly grasp the dialectical unity between high-quality development and high-level protection, consider ecological and environmental protection work in the overall situation of implementing the new development concept, constructing a new development pattern, and promoting high-quality development, create a vivid picture of co building and sharing a beautiful China, continuously draw an updated picture of a beautiful China, and make new contributions to accelerating the modernization of harmonious coexistence between humans and nature. In recent years, China has implemented a number of key ecological protection and construction projects in the western region, such as water and soil conservation, returning farmland to forests, returning grazing land to grassland, natural forest protection, Three-North Shelterbelt Program, wetland protection and restoration, wildlife protection and nature reserve construction, optimizing the pattern of land space development and protection, strengthening the management and control of ecological environment zoning, achieving significant results in ecological environment protection and governance, and continuously improving the quality of ecological environment in the river basin. In 2022, the proportion of excellent water quality in the national control section of the Yangtze River Basin reached 98.1%, an increase of 16.3 percentage points from 2015; The proportion of Class I to III surface water sections in the Yellow River Basin reached 87.5%, an increase of 5.6 percentage points year-on-year. The population of wild animals has significantly increased. In the Three Rivers Source National Nature Reserve of the "China Water Tower", the population of Tibetan antelopes has increased to over 70000, and the protection level has been lowered from "endangered species" to "near endangered species". The ecological security barrier continues to be reinforced, and the cumulative implementation of returning farmland to forests and grasslands has exceeded 320 million acres, significantly increasing forest coverage. To promote high-quality development through high-level protection, it is necessary to continuously optimize the pattern of national spatial development and protection. Land is the spatial carrier of green development, and national spatial planning is the guide for spatial development, the spatial blueprint for sustainable development, and the basic basis for various development, protection, and construction activities. Continuously optimizing the spatial development and protection pattern of the western region can effectively improve resource utilization efficiency, firmly maintain the bottom line of security and development, and ensure the effective investment land demand for high-quality development. To promote high-quality development through high-level protection, it is necessary to further strengthen ecological and environmental zoning control, continuously improve the ecological and environmental zoning control system covering the entire area, and provide high-quality development for the western region
