Embodiment approach

[0024] In practice, the main problem of the pattern optimization mode of land consolidation projects can be attributed to the design of patches and corridors to meet the individual ecological needs of local species to a certain extent. The spatial distribution and size of patches and corridors are spatial patterns, and the determination of the size of these patches and the specific location of corridors must take into account the landscape process, that is, the analysis of landscape functions.

[0025] Such as figure 1 As shown, it is divided into the protection of original natural patches, the construction of corridors and key nodes, and through the investigation of natural patches in the land consolidation area, the classification and attributes of various green spaces (such as woodland, shrubs, grasslands), Field investigation of water bodies (ponds, rivers, lakes), etc.; at the same time, establish a GIS database such as land use, landscape characteristics, etc., and analy...

Abstract

The invention discloses a landscape pattern optimizing mode for a land consolidation project, which optimizes a land consolidation project planning mode for changing a regional landscape pattern in large scale by using the thought of landscape ecology and starting from the overall pattern of the landscape ecology. The overall landscape pattern analysis comprises a landscape suitability evaluation method supported by a GIS and ecological reconstruction and protected mode of a landscape level, selection of a key position of a recovery mode and construction of a sustainable landscape ecology pattern (figure 1) through construction of a minimum cost surface model and protection, reconstruction and combination of a key point, a line and a local part (surface). The main implementation comprises three levels, namely investigation, attribute classification and protection of original natural patches, construction of channels, roads and ecological hedge galleries and construction of key gallery crossing points.

Description

technical field [0001] The invention belongs to the field of environmental ecology, and mainly relates to a concept and a practical method of a landscape pattern optimization mode in land consolidation. Background technique [0002] With the continuous development of our country's economy and society, a large amount of land is needed for construction. As an important means of increasing cultivated land, land consolidation plays an important role. From 2001 to 2007, my country's land consolidation has accumulated an investment of more than 46 billion yuan and carried out more than 3,000 projects, which has vigorously promoted the development of my country's land consolidation. Land consolidation is also a resource re-allocation process combining macro and micro. Along with the process of land consolidation, the land use structure is also readjusted (at the level of macro allocation), so that under a given pattern of elements, each element can be recombined, and the efficienc...
