9. 保持水土: 森林树冠可以滞留降水而避免对地表的直接冲刷, 并积蓄雨水．树木的根系能固定土壤、吸收水分．落叶、枯枝也能吸收相当数量的水分, 减少地表径流, 防止水土流失．

9. Soil and Water Conservation: The forest canopy can retain precipitation to prevent direct erosion of the surface and accumulate rainwater. The roots of trees can stabilize the soil and absorb moisture. Leaves and withered branches can also absorb a considerable amount of water, reduce surface runoff, and prevent soil erosion.

10. 净化空气: 森林有多方面净化空气的功能．首先它保持了大气中氧和二氧化碳（CO2）平衡．森林是氧气的主要制造者和二氧化碳的消耗者, 它使得由於工业发展和人口增加造成大气中二氧化碳的浓度增加得到平衡．其次, 森林可以降低大气中有害气体的浓度．它不仅能阻挡有害气体, 而且能过滤和吸收有害气体；再次, 减少空气中放射性物质．森林能阻挡、过滤、吸收放射性物质；第四, 减少空气中的灰尘, 森林能阻挡、过滤和吸附空气中的灰尘．还能固定地面上的尘土；第五, 减少空气中的细菌．树木可以分泌挥发性物质, 有杀菌和抑制细菌的作用．

10. Purification of Air: Forests have multifaceted functions in purifying the air. Firstly, they maintain the balance of oxygen and carbon dioxide (CO2) in the atmosphere. Forests are the main producers of oxygen and consumers of carbon dioxide, which helps to balance the increased concentration of CO2 in the atmosphere due to industrial development and population growth. Secondly, forests can reduce the concentration of harmful gases in the atmosphere. Not only can they block harmful gases, but they can also filter and absorb them. Thirdly, they decrease the amount of radioactive substances in the air. Forests can block, filter, and absorb radioactive materials. Fourthly, they reduce dust in the air by blocking, filtering, and adsorbing dust particles in the air, as well as fixing dust on the ground. Fifthly, they decrease the number of bacteria in the air. Trees can secrete volatile substances that have bactericidal and antibacterial effects.

11. 狗吠深巷中，鸡鸣桑树颠。

11. A dog barks in the deep alley, crows caw on the mulberry trees.

12. 调节气候: 森林对温度、湿度、风力都有调节作用．大面积的森林能调节大范围甚至全球的气候．小面积的林带也能起到降温、增湿及净化空气的作用．

12. Climate Regulation: Forests have a regulating effect on temperature, humidity, and wind. Large areas of forests can regulate climate over wide ranges, even globally. Even small strips of forest can help cool down the temperature, increase humidity, and purify the air.

13. 什么藤结什么瓜，什么树开什么花。

13. As the vine is, so will be the gourd; as the tree is, so will be the flower.

14. 吃桔子不忘洞庭山，乘风不忘栽树人。

14. Eating oranges doesn't forget Dongting Mountain, riding the wind doesn't forget the tree planter.

15. 人投人，鸟投林。

15. People return to people, birds return to the woods.

16. 八月桂花香又香，大树靠的根来养。

16. In August, the osmanthus fragrance is strong and strong, the big tree relies on its roots for nourishment.

17. 人起心发，树起根发。

17. When a person's heart is stirred, so is the tree's root stirred.

18. 曾生长着茂密的森林, 后来由於自然的和人为的原因, 森林面积不断减少．现在世界森林面积约有28 亿公顷, 森林覆盖率约为22％．世界森林的分布很不均衡, 主要分布在非洲和南美洲的热带雨林区、北美洲和俄罗斯的亚寒带针叶林区等．

18. Once densely forested, the forest area has continuously decreased due to both natural and man-made causes. Currently, the world's forest area is approximately 2.8 billion hectares, with a forest coverage of about 22%. The distribution of the world's forests is very uneven, mainly found in the tropical rainforests of Africa and South America, the subarctic coniferous forests of North America and Russia, and other regions.

19. 十年树木，百年树人。

19. It takes ten years to grow a tree, a hundred years to cultivate a person.

20. 没有梧桐树，引不到凤凰来。?>

20. Without a wutong tree, you cannot attract a phoenix to come.

21. 十年栽树，百年歇凉。

21. Plant trees for ten years, enjoy the shade for a hundred years.

22. 财多惹祸，树大招风。

23. 立如松，坐如钟，卧如弓，行如风。

23. Stand like a pine, sit like a bell, lie like a bow, walk like the wind.

24. 保护农田: 森林和防护林带能减轻风、旱、涝等灾害．林带可以使风速大大降低, 水分挥发量随之减小, 湿度相对增大．

24. Protecting farmland: Forests and shelterbelts can alleviate disasters such as wind, drought, and flooding. The shelterbelts can significantly reduce wind speed, thereby decreasing the amount of water evaporation and increasing the relative humidity.

25. 此外, 森林还具有维护生态平衡、美化环境、促使人体健康等方面的作用．

25. In addition, forests also play a role in maintaining ecological balance, beautifying the environment, and promoting human health.

26. 涵养水源，保持水土:雨水降落到森林后，首先会受到树冠的阻留，顺着树干流到地面后，再被盘根错节的树根缠住，又因森林土质疏松，一部分水又渗入地下，成为地下水，这样，从地表直接形成径流的水就减少了许多，不易造成山洪，避免大水冲刷地表导致水土流失。

26. Water Conservation and Soil and Water Conservation: After rain falls on the forest, it is first intercepted by the tree canopy, then flows down the trunk to the ground, and is then entangled by the interwoven roots. Because the forest soil is loose, some of the water seeps into the ground to become groundwater. As a result, the amount of water that directly forms runoff from the surface is greatly reduced, which is less likely to cause flash floods and prevents heavy water from eroding the surface and causing soil and water loss.
