Embodiment Construction

[0048] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0049] like figure 1 As shown, the calculation and risk determination method of the regional ecosystem service dominance degree of the present invention comprises the following steps:

[0050] (1) Statistics of the natural environment data, socio-economic data and ecological resource data of the evaluated area, and draw the topographic map of the evaluated area;

[0051] (2) Select ecosystem function factors related to human survival needs;

[0052] (3) Calculate the ecosystem service dominance T according to the ecological resource data h ; and draw the interannual variation curve of ecosystem service dominance;

[0053] (4) Use the positive and negative bidirectional watershed algorithm to process the inter-annual variation curve of the ecosystem service dominance degree, and obtain the watershed value X of the positive ecosystem service dom...

Abstract

The invention discloses a calculation and risk judgment method for a service dominance degree of a local ecological system. The calculation and risk judgment method comprises the following steps: on the research basis of service consumption of an ecological system, calculating ecological system service provided by ecological system functions in an area and corresponding service consumption essential for living of human beings inside the area, establishing a local ecological system service dominance degree model, taking the ecological system endurance capability and the sustainable developmentpotential into account, judging a service dominance degree threshold which can affect the risks of the ecological system by using a positive/negative bidirectional watershed algorithm, quantitativelypre-judging the risk degree of the ecological system, and performing degree quantitative analysis upon the ecological system service risk situations according to calculation results. The evaluation conclusions of ecological system service are highly related to natural environment data and social economic data of an evaluated area, reasonable utilization of local ecological resources is effectivelyinstructed, excessive consumption of ecological resources is warned in advance, and disordered damage of social economic activities to ecological environments is avoided.

Description

technical field [0001] The invention relates to a method for calculating the dominance degree of regional ecological system services and judging risks. Background technique [0002] At present, the safety and risk status of the ecosystem has attracted more and more researchers' attention, and how to accurately obtain the evaluation results in line with the actual situation has become a constant pursuit of the goal. Ecosystem service evaluation methods are divided into many types according to research principles, cultural concepts, philosophical views and school ideas, but the evaluation of ecosystem services is currently divided into three directions: emergy analysis method, material quality evaluation method and value quantity evaluation method . Emergy analysis method is based on the basic unit of measurement of solar value, based on the theory of energy law, systematics, and system ecology, and classifies various forms of energy in ecosystems and economic systems as sola...
