1. The rich connotation of sustainable development Sustainable development is a new development concept proposed in the 1980s. It was produced in response to the changes of the times and the needs of social and economic development. Sustainable development refers to development that meets the needs of the present without compromising the ability of future generations to meet their own needs. Sustainable development means maintaining, rationally using and improving the natural resource base that supports ecological resilience and economic growth. Sustainable development also means incorporating environmental concerns and considerations into development plans and policies, rather than representing a new form of conditionality on aid or development funding. The three main characteristics of sustainability: ecological sustainability, economic sustainability and social sustainability, are interrelated and inseparable. Ecological sustainability is the foundation, economic sustainability is the condition, and social sustainability is the common pursuit of mankind. The sustainable, stable, and healthy development of the natural, economic, and social composite system should be. The core idea of ??sustainable development is that healthy economic development should be based on ecological sustainability, social justice and people's active participation in their own development decision-making; the goals it pursues are: to satisfy various human needs, Individuals must be fully developed; resources and the ecological environment must be protected and not pose a threat to the survival and development of future generations; it pays special attention to the ecological rationality of various economic activities, emphasizing that economic activities that are beneficial to resources and the environment should be encouraged, Otherwise it should be discarded. The emergence of the theory of sustainable development pointed out a path for the development of the human world that combines environment and development, and provided an innovative thought model for the coordinated development of environmental protection and human society. Its essence is to closely link economic development with resource conservation and environmental protection to achieve a virtuous cycle. The concept of sustainable development requires actively solving environmental problems in development, not only promoting human development, but also promoting harmony with nature. Mainly manifested in: from development aiming at pure economic growth to comprehensive development of economy, society and ecology, from material-oriented development to people-oriented (the purpose of development is to meet people's basic needs and improve people's quality of life) The development of the country has shifted from focusing on immediate and local interests to the development of long-term and overall interests, and from development driven by material resources to development driven by non-material resources or information resources (technology and knowledge). 2. The Proposition of Sustainable Development Strategy The so-called sustainable development strategy refers to the action plan and program to achieve sustainable development. It is a general term for achieving sustainable development in multiple fields. It aims to achieve development goals in all aspects, especially social and economic. Coordinate with ecological and environmental goals. In June 1992, the United Nations Conference on Environment and Development was held in Rio de Janeiro, Brazil. The conference proposed and adopted the global sustainable development strategy - "Agenda 21", and required all countries to formulate their own sustainable development strategies based on their own national conditions. , plans and countermeasures. On July 4, 1994, the State Council approved my country's first national sustainable development strategy - "China's White Paper on Population, Environment and Development in the 21st Century". The proposal of the sustainable development strategy marks a major revolution in the concept of human development since the industrial revolution, and it marks that it is a new development concept and action program that is conducive to the healthy movement of mankind into the 21st century. Sustainable ecological civilization will become the main theme of the development of human society in the 21st century. 3. The necessity of implementing a sustainable development strategy. In terms of resources: With the continued growth of the world's population and economic development, humankind's increasing demand for resources and large-scale exploitation and consumption have led to the weakening, degradation, depletion of the resource base, and the shortage of fresh water resources. The price of oil and other energy sources has risen, and land and mineral resources have been severely damaged by predatory activities. Maintain the earth's resources and maintain biodiversity to ensure the sustainable use of resources. Environmental aspect: Mainly manifested in two categories: environmental pollution and ecological damage. Strengthening environmental protection is an inevitable requirement to promote the transformation of economic growth patterns, eliminate poverty, and promote overall social progress. 4. The significance of implementing a sustainable development strategy. Implementing a sustainable development strategy is conducive to promoting the unity of ecological benefits, economic benefits and social benefits. It is beneficial to promote the transformation of economic growth mode from extensive to intensive and coordinate economic development with population, resources and environment. It is conducive to the sustained, stable and healthy development of the national economy and improves the people's living standards and quality. It is conducive to promoting the process of new industrialization. It is conducive to the adjustment of agricultural economic structure, protection of ecological environment and construction of ecological agriculture. 5. Scientific concept of development The traditional concept of development focuses on the growth of material wealth and ignores the all-round development of people and the overall progress of society; it simply takes the growth of GDP as the core indicator to measure economic and social development and ignores humanities, resources, Environmental indicators; simply regard nature as the object of human survival and development, ignoring that nature is first and foremost the basis for human survival and development. Under the influence of the traditional development concept, although mankind has accumulated abundant material wealth, it has also paid a huge price for it.

The phenomena of resource waste, environmental pollution and ecological destruction are common and increasing. However, people's living standards and quality often fail to improve correspondingly with economic growth, and many social and environmental problems even endanger future survival.

To solve these contradictions and problems in the historical process, we must abandon the influence of traditional development concepts and development models, and move forward with the development concept
