土壤不仅是林木赖以扎根固定的基地,而且还为林木生长提供所需要的各种营养物质和水分。土壤条件的好坏是影响林木生长、森林群落生产力的重要因素之一。同时,在森林群落发展演替的过程中,受森林的影响,土壤的理化性质也会相应地发生改变。土壤与林木之间的相互关系越来越被人们所重视,世界各国都投入了大量的人力、物力,开展这方面的研究,并且获得了大量有价值的资料,丰富了人们在这方面的知识。
Not only is the soil the root of the tree, but it also provides all kinds of nutrients and moisture needed for forest growth. Soil conditions are good or bad forest growth, forest productivity is one of the important factors. At the same time, in the process of forest community succession, due to the influence of forest, the physical and chemical properties of soil will also change accordingly. The relationship between soil and tree is getting more and more attention. All the countries in the world have invested a lot of manpower and material resources to carry out research in this field, and have obtained a lot of valuable information to enrich people’s knowledge in this field .
