Problems solved by technology

However, the national ecological geography division is based on regional differences to explore the division of units of different scales across the country. Most of the studies are on a large scale, and the division is based on natural elements. It is rarely combined with the domestic administrative system, making the comprehensive natural division The elements are single, the development of natural characteristics and environmental management units is not systematic, and my country lacks methods for comprehensive planning and decision-making at the county level

Embodiment approach

[0065] According to a preferred embodiment of the present invention, the scores of the ecological land under the low safety level, the ecological land under the medium safety level, and the ecological land under the high safety level are respectively recorded as 4, 2 and 1.

[0066] According to the present invention, in the water security pattern, using the GIS spatial overlay analysis function, the evaluation results of the water source protection safety factors and the rain and flood protection safety factors are weighted or graded. The Delphi method or empirically determines that the weight of the water source protection safety factor is 0.5, and the rain and flood protection safety factor is 0.5, and the evaluation results and evaluation distribution map of the water safety pattern are obtained.

[0067] According to a preferred embodiment of the present invention, the index layer of the geological disaster safety pattern includes slope, vegetation coverage and geological ...

Embodiment

[0307] Taking Wusheng County of Sichuan Province as an example, the division method of landscape comprehensive management units is explained.

[0308] Collect various raw data of Wusheng County, and divide the administrative area of ​​Wusheng County into multiple grid units of 100m*100m.

[0309] Considering the management unit of landscape characteristics in Wusheng County from the three indicators of ecological security factor, shrinkage development factor and characteristic style factor, arcgis software is used to score and superimpose the evaluation factors.

[0310] According to the expert scoring method, using the GIS spatial overlay analysis function, according to the index layer of the set ecological security factor, the scoring results of each grid unit are obtained, and the scoring results of the index layer are weighted and superimposed to obtain the grid unit in the pattern layer. The scores of the water security pattern, the geological disaster security pattern an...

Abstract

The invention discloses a landscape integrated management unit division method. The method comprises the steps of determining evaluation factors of landscape feature management unit division; obtaining an evaluation result of the evaluation factor; grading the evaluation results of the evaluation factors, and determining the category of the development direction. According to the invention, different landscape management unit features of the target area are obtained by evaluating, superposing and grading the landscape feature units of the target area, and the landscape management unit of the target area is combined with the administrative management unit to perform differentiated management on the target area. According to the invention, landscape unit planning is carried out from the county scale, comprehensive planning is carried out on the target area by combining the natural and humanistic characteristic comprehensive management unit, and correction is provided for existing planning development.

Description

technical field [0001] The invention belongs to the field of landscape planning, and in particular relates to a method for dividing landscape comprehensive management units. Background technique [0002] Internationally, landscape management and decision-making is mainly the classification and division of landscape units. Landscape units are spatially heterogeneous areas divided according to certain natural characteristics. Later, social attributes and data are added to the natural characteristics for correction. At the same time, the classification results of landscape units can be used to guide and revise planning and policy making. [0003] Domestic research on landscape characteristic units is generally based on the division of natural elements, and landscape characteristic units are divided on a national scale or a regional scale. However, the national ecological geography division is based on regional differences to explore the division of units of different scales ac...
