Engineering Contradiction Analysis
1Adaptability or versatility
If a unified calculation method for ecosystem service values is not implemented, then evaluation can only be performed for past data, but future ecosystem conservation scenarios cannot be analyzed
Solution Approach 1:
The evaluation system is segmented into distinct functional modules: data acquisition module for collecting ecosystem and conservation scenario data, network structure extraction module for identifying relationships between ecosystem elements, ecosystem function estimation module for calculating functional values, and economic value calculation module for determining conservation worth. This modular segmentation enables the system to handle future scenario analysis while maintaining manageable complexity through standardized interfaces between modules.
Solution Approach 2:
The system performs preliminary actions by establishing a unified calculation framework in advance that incorporates budget constraints and ecosystem network structures. This pre-established framework allows future conservation scenarios to be analyzed by simply inputting different scenario parameters, eliminating the need to redesign the evaluation methodology for each future scenario and enabling forward-looking analysis capability.
2Measurement precision
If ecosystem conservation scenarios are evaluated using a unified calculation method, then future impacts can be accurately assessed, but the calculation complexity increases
Solution Approach 1:
The system manages calculation complexity by parameterizing the unified calculation method, allowing future impact assessments to be performed by changing input parameters (conservation scenario data, budget constraints, ecosystem specific data) rather than altering the core calculation framework. This parameter-driven approach maintains measurement precision for future scenarios while controlling computational complexity through reusable calculation templates.
Solution Approach 2:
The ecosystem function network serves as an intermediary structure that bridges raw ecosystem data and economic value calculations. This network representation simplifies complex ecosystem relationships into standardized nodes and edges, enabling accurate future scenario assessments through consistent network-based calculations while reducing the overall computational complexity by providing a structured intermediate representation.

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.
