Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0048] A landscape pattern-based ecological risk assessment method for overall township land use planning, including the following steps:

[0049] Step 1. Select and determine the evaluation object

[0050] This application is aimed at the township overall land use plan, so select the actual township administrative area, and take the overall land use plan of the specific township administrative area as the evaluation object;

[0051] As a specific embodiment of the present invention, as attached figure 1 As shown, the present invention has selected Heping Yi nationality township located in the middle of Jinkouhe District, Leshan City, and the total land area is 4221.22hm 2 . The "Master Plan for Land Use in Heping Yi Nationality Township, Jinkouhe District, Leshan City (2006-2020)" (hereinafter referred to as the "Plan") is a programmatic do...

Abstract

The invention discloses a rural land utilization overall planning ecological risk evaluation method based on a landscape pattern. The method comprises the following steps: step 1, selecting and determining an evaluation object; step 2, dividing evaluation units; step 3, making a spatial distribution thematic map; step 4, ecological condition analysis of evaluation grid units, including landscape fractal dimension evaluation, landscape diversity evaluation, landscape fragmentation degree evaluation and landscape separation degree evaluation; step 5, an ecological risk evaluation method; and step 6, comprehensive evaluation of regional ecological risks. Overall planning of rural land utilization is taken as an object, quantitative expression between landscape pattern indexes and ecological risks is constructed, and measurement and determination of regional ecological risks are realized through quantitative data, so that a scientific basis is provided for ecological risk prevention and control of planning.

Description

technical field [0001] The invention relates to a land risk assessment method, in particular to a landscape pattern-based ecological risk assessment method for overall township land use planning. Background technique [0002] The overall land use plan is the overall arrangement of land use in a certain administrative region in the future, which has the characteristics of forward-looking and long-term, and its implementation will have a profound impact on the structure and function of the regional ecological system. In order to strengthen the protection of land ecological environment and improve the quality of planning, it is necessary to introduce the ecological risk assessment mechanism into the final decision-making analysis, so as to reduce and avoid the adverse ecological effects that may be caused by the implementation of planning. Compared with the ecological risk of a single project, the ecological risk of the overall planning of land use involves a large area, many f...
