First, establish the forestry strategic thought with "ecological construction, ecological security and ecological civilization" as the core in the whole society. Historically, forests have accumulated wealth for the country and supported socialist construction. Due to the development of industry, forestry has become the main body of ecological construction and the foundation of sustainable economic and social development in China. The new changes in the orientation and nature of forestry require that forestry and even the whole economic and social development should implement the strategic thinking of "ecological construction, ecological security and ecological civilization" and study and solve a series of major problems with new ideas. It is undoubtedly important to further clarify the concept of building forest ecosystem, and according to the different natural conditions of forests, to maximize the success of forest management in the ecosystem with the greatest energy and the best effect. For example, the increase of forest area and accumulation is the basic goal of forestry development. However, under the condition of expanding the same area and increasing the same accumulation, it is necessary to consider the integrity of forest functions and the formation of forest ecosystem. For example, in some places, forest resources are scarce, so it is necessary to reserve forest resources and recuperate. However, in a certain rest period, the restoration and improvement of forest ecosystem must be considered, that is, the increase of ecosystem diversity, species diversity and genetic diversity should be emphasized.

Second, we should further study the optimal layout of forest coverage rate from the whole, source and root. The scientific layout of forest is the basis to ensure the best ecological function of forest under specific natural conditions, and it is also the requirement of the development of advanced forestry productivity. At present, China's forest coverage rate has increased rapidly, but the overall ecological function of the country is not good, mainly because the forest layout is unreasonable. With the development of society, the geographical scope of forestry is shrinking. Different geographical regions in urban and rural areas have different leading demands for ecological functions, so should the leading ecological functions of forests. For example, water and soil conservation forests should be built around river basins and lakes, and water conservation forests should be built in urban river basins.

Third, attach great importance to the construction of forest quality. Compared with developed countries in forestry, the gap between China and developed countries is still not small. China has mountainous areas (accounting for 69% of the land area) and vast sandy areas (desertification land accounts for 65,438+08.2%), and the precipitation distribution is extremely uneven. In order to ensure the ecological security of modern countries and realize the basic balance of ecological supply and demand, it is objectively required that forests must be of high quality. On the one hand, the quality of existing forests should be improved. There are still some problems in the existing forests, such as the aging of shelter forests (such as windbreak forests, sand-fixing forests, soil and water conservation forests), excessive logging of natural forests, and single function of artificial forests. No matter how much the forest area of our city increases, the existing forest will still be the main part of China forest after several decades. Therefore, active management measures should be taken to strengthen cultivation and improve the quality of this main forest as soon as possible. On the other hand, the newly added forests should be parallel in quantity and quality from the beginning, with quality as the main factor. We should focus on the long-term and start with basic work to avoid large-scale and long-term quality transformation in the future. Secondly, forest quality construction should meet the demand of local economy, society and natural environment for forest leading function. It should be pointed out that different geographical areas and natural conditions have different forest functions. To improve the quality of forests, we should pay attention to giving full play to the leading role of forests under specific local conditions. For example, the leading functions of upstream and downstream forests in the south and north, mountainous and sandy areas and river basins are different, and the corresponding quality construction standards should also be different.

The fourth is to put the construction of water conservation forest in a prominent position. The shortage of water resources, especially in the northern region, is a major problem of China's sustainable development. Forests are natural reservoirs and natural water purifiers. Under the global warming environment, strengthening the construction of water conservation forest is a strategic issue related to the survival and development of the country. The construction of water conservation forest is a systematic concept, including forests to increase runoff from the source of rivers, forests to maintain glacier snow line, forests to maintain precipitation in mountainous areas, forests to maintain water and soil in rivers and reservoirs, forests to ensure water supply and clean water in cities and towns, forests to improve wetland functions, and so on.
