Abstract

The invention provides a method for remote sensing quantitative estimation on the woodland site quality. A soil organic matter, a soil humus layer, the thickness of soil, a gradient, the slope aspect and the altitude are selected as leading factors by analyzing a grading basis and a grading criterion of four grades including grade I, grade II, grade III and grade IV of the traditional site quality, estimation and inversion of all thematic information are realized on the basis of a 3S technique by utilizing relevant ground information of regional ground actual measurement and investigation, a score table of the woodland site quality is established by adopting a quantification theory, and the verification precision is 81%. The method has the advantages of strong reality, time saving and labor saving and is important in reflecting the change of the regional woodland site quality by utilizing the advantages of remote sensing time; in addition, the precision of all estimation results of the method is increased, and an important basis is provided for optimization management of woodland.

Description

technical field

[0001] The invention belongs to the technical field of management and application of forest resources, and in particular relates to a method for remote sensing quantitative estimation of forest site quality. Background technique

[0002] The quality of forest land site is a complex of interconnection and interaction of climate, geology, landform, soil and various biological conditions in a certain area, and it is the environmental condition for forest growth. The quality of forest land site has great influence on the growth of trees. Studying the quality of forest land site can provide an important basis for the determination of measures such as suitable land and trees, silvicultural planning, forest land selection, and suitable afforestation technology, and realize the estimation of various benefits of forest management, timber production costs, and afforestation investment. . Therefore, the study of forest site quality plays an important role in improving...
