2000-2020年福州市300米生态维持程度数据集（第一版）

数据的主要内容是福州市在2000-2010年期间、2010-2020年期间，2000-2020年期间的生态维持程度，基于土地利用数据得到的福州市300米分辨率的2000年、2010年、2020年的生态安全水平数据，再在这个数据的基础上，进行差值计算，得到福州市三个时间段的生态维持程度数据，参考相关文献与请对福州市较为熟悉的专家老师进行评价与修正，最终得到福州市2000-2010，2010-2020，2000-2020的生态维持程度数据集。此数据在项目中的作用：研究福州市区域内的生态维持状况，可以在一定程度上为不同自然带的生态维持评价对比提供参考依据。

The core content of this dataset is the ecological maintenance level of Fuzhou City across three time periods: 2000–2010, 2010–2020, and 2000–2020. The dataset was developed through the following workflow: First, 300-meter resolution ecological security level data for Fuzhou City in 2000, 2010, and 2020 were generated based on land use datasets. Next, difference calculations were conducted on this multi-temporal ecological security level data to derive preliminary ecological maintenance status data for the three target periods. Subsequently, the preliminary results were evaluated and revised by referring to relevant academic literature and consulting experts familiar with Fuzhou City. Finally, the finalized ecological maintenance level dataset covering the three aforementioned periods was obtained. The role of this dataset in the corresponding project is to support research on the regional ecological maintenance conditions of Fuzhou City, and it can provide a reference for comparative evaluations of ecological maintenance across different natural zones to a certain extent.
