Description

Technical Field

[0001] The present invention relates to the technical field of ecological environment monitoring and restoration, and particularly to an ecological restoration dynamic simulation and interactive experience system. Background Art

[0002] Ecological restoration refers to the process of intervening in damaged or degraded ecosystems through scientific means to restore their ecological functions and biodiversity. With the acceleration of industrialization and urbanization, ecological environment problems have become increasingly severe. Traditional ecological restoration methods mostly rely on static assessment and experience-based decision-making, making it difficult to dynamically simulate the long-term effects of restoration plans, resulting in problems such as unreasonable resource allocation and low restoration efficiency. How to achieve dynamic simulation and real-time interactive optimization of the ecological restoration process has become a key challenge in improving the efficiency of ecological governance.

[0003] In the prior art, some systems obtain environmental data by combining satellite remote sensing and ground monitoring, and predict the ecological evolution trend through simple mathematical models. For example, analyzing the vegetation coverage using remote sensing images and establishing a linear regression model in combination with historical meteorological data to simulate the diffusion path of pollutants. Although such methods can preliminarily evaluate the restoration effect, the model parameters are fixed and cannot adapt to dynamic environmental changes.

[0004] Although the above technologies provide important support for ecological restoration, they also have obvious limitations. First, due to the lack of an effective multi-source data fusion mechanism, it is difficult to achieve seamless docking between different types of data, resulting in low information utilization rate. Second, most of the existing prediction models are based on simple statistical relationships or shallow learning architectures, and cannot fully capture the dynamic change characteristics of ecosystems in complex environments. Finally, in terms of user experience, traditional methods do not provide intuitive three-dimensional visualization tools, making it difficult for decision-makers and technicians to directly feel and understand the potential changes and their effects in the ecological restoration process. The existence of these problems urgently requires an ecological restoration dynamic simulation and interactive experience system that can integrate a variety of advanced technologies to achieve high-efficiency, precision, and user-friendly performance.
