Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a unified calculation method is introduced, then the ability to analyze future conservation scenarios is improved, but the device complexity increases
Solution Approach 1:
The system segments the ecosystem evaluation into distinct computational modules: data acquisition module for collecting ecosystem data, network structure extraction module for identifying relationships, ecosystem function estimation module for calculating functions, and economic value calculation module for determining monetary values. This segmentation allows the complex unified calculation method to be implemented through manageable, specialized components that can be developed and maintained independently.
Solution Approach 2:
The system implements a universal calculation framework that handles multiple ecosystem services (water supply, carbon storage, biodiversity, etc.) through a single integrated methodology. The ecosystem function network serves as a universal structure that can represent different types of ecosystem functions and their interactions, allowing the same computational approach to be applied across diverse conservation scenarios without requiring separate specialized systems.
2Measurement precision
If ecosystem function network estimation is performed, then measurement precision of ecosystem values is improved, but loss of time in computation increases
Solution Approach 1:
The system performs preliminary extraction of network structures from ecosystem data before conducting detailed function estimations. By pre-identifying the relationships and connections between ecosystem components in advance, the system prepares the computational framework that accelerates subsequent calculations. This preliminary structuring allows the detailed ecosystem function estimations to proceed more efficiently while maintaining high precision.

AI summary
An environment evaluation system stores first data on an ecosystem of a conservation target area, second data on land use of the conservation target area, and third data on a conservation scenario in the conservation target area. The environment evaluation system extracts a network structure where areas having natural capital in the conservation target area are nodes based on the second data, estimates an ecosystem function network representing types of ecosystem functions of the nodes and time-related functions of interactions between the nodes based on the first data, the third data, and the network structure, calculates an economic value of a change in the ecosystem function of the node using a conservation scenario for the node based on a budget constraint related to the conservation scenario for the node which is calculated from the ecosystem function network and the third data, and outputs the economic value.
