本研究利用Sen+MK方法分析了特定区域内的ET(蒸散发)趋势,重点评估了使用遥感数据的ET空间变化。该方法结合了Sen斜率估算器和Mann-Kendall(MK)检验,为评估长期趋势提供了稳健的框架,同时考虑了时间变化和统计显著性。 主要过程与结果: 1.ET趋势可视化:研究利用ET数据,通过ET-MK和ET趋势图展示了蒸散发在不同区域的空间和时间变化。这些图通过颜色渐变表示不同的ET水平及其趋势。 2.Mann-Kendall检验:应用MK检验来评估ET趋势的统计显著性。检验结果以二元分类图呈现,标明ET变化的显著性,帮助识别出有显著变化的区域。 3.重分类结果:通过重分类处理,将区域根据ET变化的显著性进行分类,从而聚焦于具有显著变化的区域。这一过程确保分析集中在具有实际意义的发现上。 4.最终输出:最终结果以栅格图和png图的形式呈现,支持各种应用,包括政策规划、水资源管理和土地利用变化分析,这些都是基于详细的时空分析。 ------------------------------------------------------------------- 文件夹构造: data文件夹:原始数据,支持分析的基础数据(MOD16A2H ET数据 宁夏部分)。 results文件夹:分析结果与可视化,展示研究成果。 Sen+MK_optimized.py:主分析脚本,适合批量数据处理和自动化分析。 Sen+MK.ipynb:Jupyter Notebook,复现可视化地图。
### NXP LS1028A RDB Specifications and Usage #### Hardware Overview The NXP LS1028A Reference Design Board (RDB) is designed to support the development of applications based on the Layerscape LS1028A processor. This board includes a variety of interfaces and peripherals that facilitate comprehensive testing and evaluation of hardware capabilities[^1]. The LS1028 platform supports advanced features such as SerDes modules, which can be configured through Reset Configuration Word (RCW), allowing flexible pin multiplexing settings. #### Key Features - **Processor**: Based on ARM Cortex-A72 cores. - **Memory Support**: DDR4 SDRAM with ECC support. - **Networking Interfaces**: Multiple Gigabit Ethernet ports supported by integrated PHYs. - **Peripheral Connectors**: USB, PCIe, SATA connectors available for expansion options. - **Debugging Tools**: JTAG interface provided for debugging purposes. #### Software Development Environment Setup For setting up the software environment specifically tailored for LS1028ARDB, one approach involves building `sdboot` followed by constructing the Linux kernel using tools like FlexBuild. An example command line would look something similar to this: ```bash flex-builder -c linux:linux:LSDK-19.06-V4.19 -a arm64 ``` This setup ensures compatibility between the operating system and the specific architecture requirements of the LS1028A SoC[^3]. #### Pin Multiplexing via RCW An important aspect when working with LS1028A concerns configuring pins according to application needs. By defining appropriate values within the RCW file during boot initialization, developers gain control over how each physical pin behaves—whether it serves general-purpose I/O functions or specialized communication protocols involving SerDes channels.
