Method for regulating and controlling pattern of protective forest system

Abstract

The invention discloses a method for regulating and controlling a pattern of a protective forest system. The method comprises the following steps of: 1, acquiring land utilization landscape characteristics of a river basin in each period, and analyzing the evolution characteristics of the land utilization pattern of the river basin; 2, analyzing the driving factors of the change of the landscape type of the river basin and the main driving power of the change of the land utilization of the river basin by a principal component analysis method; 3, analyzing and comparing the condition of the ecological service function of the river basin in each period in the aspects of water source conservation, soil conservation, carbon fixation and oxygen release, nutrient substance accumulation, atmospheric environment purification and biodiversity protection; and 4, performing dynamic simulation by using a gray linear planning method and a Clue-s model to acquire the landscape optimized configuration scheme of the river basin. By processing satellite images in different time sequences, the relation between the change of a landscape pattern and natural, social and economic activities is uncovered, a driving mechanism which influences the evolution of the landscape pattern is analyzed, and the method for regulating and controlling the pattern of the protective forest system on the basis of landscape ecology is constructed.

Description

technical field [0001] The invention relates to the field of landscape structure optimization, in particular to a method for regulating the pattern of a shelter forest system. Background technique [0002] Shelter forest refers to a forest ecosystem with targeted protection (such as preventing avalanches, mudslides, dry wind, etc.) or direct protection. Shelter forests should also have site protection functions and functions such as recreation, carbon sequestration, and biodiversity protection. Land use is the state of social use of the earth's surface, and it is the landscape that human beings conduct long-term or periodic management of the land for their survival through relatively complete biological and technological activities. Land use pattern usually refers to the spatial structure characteristics of the landscape. The pattern analysis combining landscape structure and ecological process is the development direction of land use pattern research. Land use is a dynam...

Problems solved by technology

However, so far, studies on the optimization of land use structure have paid more attention to the optimization of land use quantity structure, but neglected the impact of land use spatial pattern on many ecological processes.

The existing land use planning system has not fully absorbed the theory of ecology, and the application of landscape ecology in land use pattern planning is still at the stage of theoretical discussion, and there is a lack of methods to implement it into the specific operational level of land use in the form of spatial planning and way
