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 abso

[0101] (1) Study on the change of forest landscape pattern in Huairou Reservoir Basin

[0102] From the perspective of the entire landscape pattern of the Huairou Reservoir Basin, a large area of ​​mountainous area is the basic landform feature of the Huairou Reservoir Basin, and woodland is the main matrix of the Huairou Reservoir Basin.

[0103] Table 2 shows the index data at the level of each landscape type in the Huairou Reservoir in each year, and Table 3 shows the index data on the landscape level in each year in the Huairou Reservoir.

[0104] The characteristics of landscape patches in this paper include: patch type area (CA), landscape percentage (PLAND), number of patches (NP), maximum patch index (LPI), mean patch area (MPS), and standard deviation of patch area. (PSSD), Landscape Shape Index (LSI), Mean Patch Shape Index (MSI).

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...
