    Abstract: Since the implementation of the major function oriented zoning, the ecological space of key ecological functional areas has continuously expanded, with a significant increase in vegetation coverage. Concurrently, there has been a dual change in population dynamics, characterized by a decrease in total population and an increase in the urban population. Furthermore, significant achievements have been made in economic and social development, and there has been a steady improvement in the functions of ecological security barriers, contributing to an alleviation of tension in human-environment relationships. During the 15th Five-Year Plan period, it is imperative to adhere to the functional orientation primarily focused on providing ecological services or products. While consolidating provisioning, regulating, supporting, and cultural ecosystem services, there is an increased emphasis on enhancing the quality of these services, thereby constructing a more diversified, stable, and sustainable ecological foundation. Furthermore, exploring compatible functions of eco-product development and utilization promote greening and decarbonization, aiming to establish an inclusive conservation approach that advances modernization characterized by harmony between humanity and nature. In the 15th Five-Year Plan period, ecological regions will not only be crucial components of the new territorial security pattern but also pillars of the new territorial development pattern. Optimization recommendations are as follows. From the perspective of strategic patterns, it is necessary to enhance the spatial connection and supply-demand interaction between ecological security barriers and the territorial development pattern. In detail, continued efforts are needed to consolidate the national ecological security barriers, optimize the pattern of key ecological functional areas, integrate the system of natural protected areas, and strictly adhere to ecological conservation red lines. Moreover, a greater focus should be on upgrading quality of ecosystem service functions through classification, fully implementing the holistic approach to protecting and restoring mountains, rivers, forests, farmlands, lakes, grasslands, and sand, actively fostering new growth drivers for green development, accelerating the establishment of a refined zoning control system, and synergistically advancing reforms and innovations of institutions and mechanisms. These measures aim to support high-quality development in ecological regions through high-standard protection.

    Subjects: Statistics >> Social Statistics submitted time 2024-03-27 Cooperative journals: 《中国科学院院刊》

    Abstract: As the fundamental goal of ecological civilization construction in the new era of China, the building of a Beautiful China is an important measure to promote the study of Chinese man-land relationships to a higher level and a new stage of development. This study takes the construction of ecological civilization of Beautiful China as the orientation, and carries on the frame design to the geographical landscape. The geographical landscape takes the elements of geoscience as the research object and makes a series of reasonable outlook about man-land system according to the interaction mechanism of human-land relationship and the influence of important uncertain factors, aiming to establish and maintain the sustainability of regional development. The geographical landscape of ecological civilization construction needs to be designed by elements, stages and regions. One of the important purposes of geographical landscape design of ecological civilization construction is to achieve the spatial balance of regional development. Therefore, its design is an extension of the spatial equilibrium model of regional development. The construction paths of different regional geographic landscapes are different. Each region should design unique construction plan of geographical landscape according to the specific characteristics of its own comprehensive development state. The reference value of United Nations’ SDGs for the geographical landscape design of ecological civilization construction in China is not as good as the relevant index system of advanced countries and regions such as the European Union and the United States, while it is of much significance to select the appropriate benchmark for the scientific and rational design of China’s geographical landscape.

  • Spatial agglomeration and environmental effects of heavy polluting industries in China: Characteristics and enlightenment

    Subjects: Statistics >> Social Statistics submitted time 2024-03-27 Cooperative journals: 《中国科学院院刊》

    Abstract: Heavy polluting industries are the important sources of industrial pollutant. Understanding the spatial agglomeration characteristics, influencing factors, agglomeration mechanism and environmental effects of China’s heavy polluting industries can help identify potential pollution risk areas to cope with increasingly severe environmental pollution problems. Based on the industrial economic data from 1999 to 2021, the spatial distribution and agglomeration characteristics of heavy polluting industries are characterized. It is found that: (1) Shandong, Jiangsu, Zhejiang, and Guangdong are the regions with high output value of the development of heavy polluting industries in the past 20 years, while Xinjiang, Inner Mongolia, Shanxi, Shaanxi, Henan, and Sichuan are the potential areas for the agglomeration of heavy polluting industries in the future. (2) Production cost (factor endowment), environmental regulation, economic development level, market share, and industrial structure are the key factors affecting the development of heavy polluting industries, and there is an obvious “inverted U” relationship between labor cost and heavy polluting industries development. (3) There is regional heterogeneity in the development of heavy pollution industries. The eastern region has a significant effect of pollution shelter, while the central and western regions have a more obvious orientation to seek low labor costs and resource enrichment. (4) The agglomeration of heavy polluting industries significantly increases the emission of industrial pollutants, and there is an obvious inverted U relationship with environmental pollution, but environmental regulations have not played a role in reducing pollution and emission. On this basis, the countermeasures and policy suggestions are further put forward to deal with the agglomeration of heavy polluting industries and reduce the potential pollution risk, providing reference to achieve the goal of Beautiful China.

  • 黄土高原生态保护和高质量发展现状、问题与建议

    Subjects: Geosciences >> Other Disciplines of Geosciences submitted time 2023-08-23 Cooperative journals: 《中国科学院院刊》

    Abstract: The ecological protection and high-quality development of the Yellow River Basin has been prioritized as a national strategy. The release and implementation of the Outline of the Yellow River Basin’ s Ecological Protection and High-quality Development Plan in 2021 have placed the Loess Plateau, located in the middle reach of the Yellow River, in a critical phase characterized by the need to sustain ecological restoration achievements while fostering socioeconomic progress. This study provides a comprehensive overview of the current conditions and issues related to ecological construction and socioeconomic development in the Loess Plateau. It proposes four specific suggestions focusing on improving ecosystem stability and sustainability, promoting a green transition in socioeconomic development, implementing scientific territorial planning, and adopting an integrated and coordinated approach to managing the entire Yellow River Basin during ecological restoration efforts. The study aims to provide scientific support for the ecological protection and high-quality development of both the Loess Plateau and the Yellow River Basin.
