KR-20260062510-A - method for building eco system

Abstract

With the purpose of providing an economically efficient method for establishing an ecosystem capable of maintaining continuous ecological benefits by performing optimization at each point in time, the present invention comprises the steps of: arbitrarily designating a plurality of ecological corridors and ecological habitats, respectively, in a desired area; performing an evaluation for each of the designated ecological corridors and ecological habitats; based on the evaluation, excluding a subordinate portion and leaving a plurality of first ecological corridors and a plurality of first ecological habitats; arbitrarily designating a plurality of second ecological corridors and a plurality of second ecological habitats; and evaluating together the remaining plurality of first ecological corridors and the plurality of first ecological habitats, along with the newly added plurality of second ecological corridors and a plurality of second ecological habitats. A method for establishing an ecological system is provided, comprising the steps of: removing a subordinate part based on the above evaluation and leaving a plurality of second ecological corridors and a plurality of second ecological habitats; and, if it is determined that the evaluation score converges by repeating the above process, not making a new designation and using the converged result as the final selected ecological corridor and ecological habitat.

Description

Method for building an ecosystem The present invention relates to a method for establishing an ecological system, and more specifically, to a method for determining the establishment of an ecological system, namely an ecological corridor or an ecological habitat, in a situation where urban development is in progress. In order to protect the ecosystem even amidst ongoing urban development, creating ecological corridors that allow animals to pass regardless of roads, as well as ecological habitats where animals can live, is an essential task for ecological conservation. However, finding the optimal solution regarding where and to what extent to create ecological corridors and habitats within a given budget is not easy. One method presented here is the single action plan approach. This method is an approach that attempts to solve all environmental problems in a single action during the urban development process. It primarily involves establishing a fixed plan and attempting to resolve problems within a short period through that plan, which can be summarized as follows. (1) Fixed plan: The single action plan approach establishes and executes a fixed plan at a specific point in time, but it has the problem of failing to reflect environmental conditions that change over time and making it difficult to cope with new issues that arise unforeseen in the initial plan. (2) Lack of consideration for long-term impact: Because this approach primarily focuses on short-term solutions, it does not adequately consider long-term ecological impacts. In other words, while the problem may appear resolved initially, new issues may arise over time along with changes in the ecosystem. (3) Cost inefficiency: A single action plan approach requires a high initial investment; while this leads to a significant influx of resources, it fails to provide sustainable ecological benefits in the long term. For example, even if a specific area is restored or protected at a high initial cost, its effectiveness may diminish over time due to a lack of continuous management and additional measures. (4) Dynamic response reflection: Since urban development is a continuously changing dynamic system, a single action planning approach has the problem of failing to adequately reflect these dynamic changes and respond appropriately to ecosystem changes over time, which can undermine long-term ecological stability. FIG. 1: Flowchart illustrating an ecosystem establishment method according to the present invention Hereinafter, specific details for implementing the present invention will be explained in detail with reference to the flowchart of FIG. 1. What is targeted in this invention and considered important in the ecosystem are ecological corridors and ecological habitats. An ecological corridor generally refers to an ecological space, such as artificial structures or vegetation, installed to prevent the fragmentation, damage, or destruction of wildlife habitats caused by roads, dams, weirs, estuary weirs, etc., and to facilitate the movement of wildlife. An ecological habitat refers to an ecological or environmental zone where a specific species of organism resides. This invention focuses on the location and area of ecological corridors and habitats rather than on the structure of ecological corridors or habitats. The following is an example. For example, let us assume that ecological corridors and ecological habitats are created in Suwon City. In an embodiment of the present invention, multiple ecological corridors and ecological habitats are arbitrarily selected or designated in Suwon City. (S10) For example, 50 can be selected. That is, 50 ecological corridors and 50 ecological habitats. An evaluation is performed on the randomly selected ecological corridors and ecological habitats. (S20) In the case of the first attempt, since there is no prior evaluation, an evaluation is performed on the newly selected ecological corridors and habitats. Evaluation criteria may include ecological connectivity, forest area, and cost. Ecological connectivity refers to the assessment of how close each ecological corridor and habitat is to one another. A high score is received if other ecological corridors and habitats are located nearby. The larger the forest area, the better the evaluation. If the cost is low, it receives a good evaluation. In this way, rank each item. For example, as in this example, if 50 items are designated for each, there will be a total of 100 items, and rankings from 1st to 100th place are determined for ecological connectivity, and of course, there may be ties. In this case, the lowest rank could be 90th. Next, rankings are determined for forest area and cost in the same way. For example, the results are as shown in Table 1. 1-1 and 1-100 are numbers assigned for convenience to identify a total of 100 arbitrarily designated ecological corridors and ecological habitats. [Table 1] In this way, the rankings for each item at a designated specifi
