With the continuous expansion of human activities, the habitats of many species are confronted with serious destruction and threats, leading to increasingly prominent ecological security issues. Therefore, it is crucial to establish an ecological security pattern that takes species habitats into consideration, so as to protect biodiversity and maintain ecological balance. Poyang Lake, as a paradise for wildlife, serves as the habitat and breeding ground for many bird species, fish, and other aquatic organisms. Taking the research scope of the peripheral region of Poyang Lake as an example, we produced the land use data for the years 2000, 2010, and 2020 on the basis of the Google Earth Engine platform and the random forest classification method. By integrating morphological spatial pattern analysis, landscape pattern indices, landscape connectivity indices, circuit theory, and long-term land use data, we developed a long-term ecological security pattern for the peripheral region of Poyang Lake from 2000 to 2020, which takes into accounts habitats for various species including fish and birds. This dataset contains various types of data, including innovative elements. In terms of data quality control and evaluation, strict quality control and evaluation processes were conducted on the data used and the predicted results, ensuring the accuracy and credibility of the data and providing effective data support and references for relevant research. The dataset not only comprises indicator data for constructing an ecological security pattern to protect species habitats but also includes historical and predicted ecological security pattern data for the peripheral region of Poyang Lake. It can provide important scientific data support and serve as references for future research on species protection and ecological security patterns in the peripheral region of the Poyang Lake.
