Dear Editor,Industrial Internet of things(IIoT) is a typical application of cyberphysical system(CPS). In the IIoT, wireless communication is an inevitable trend to replace the deployment-limited wired transmission for cases with large-scale and mobile devices. However, wireless communication gives rise to critical issues related to physical security, such as malicious detections and attacks [1].

[目的]揭示2000—2020年陕北地区典型生态系统服务的变化特征，丰富生态系统服务的系统研究框架，为陕北地区的可持续发展提供科学参考。[方法]借助INVEST模型、RUSLE方程和NDVI指数量化生态系统固碳、产水、土壤保持和食物供给服务；应用Getis-Ord G*i工具识别冷热点乡（镇、街道）的集聚特征；应用聚类和异常值分析判断生态系统服务间权衡与协同关系的时空格局。[结果]（1） 2000—2020年陕北地区单位面积碳储量、产水量、土壤保持量和食物供给量增加的区域分别占10.23%,77.91%,90.44%和47.80%;（2）各类生态系统服务均呈现出集聚分布的模式（p<0.01）,且高值集聚效应均有所增强，产水和食物供给服务的低值集聚效应同步增加，固碳和土壤保持服务的低值集聚效应减弱；（3）生态系统服务的相互作用关系逐渐由权衡主导过渡到由协同主导，多数生态系统服务间的权衡关系减弱、协同关系增强。[结论]陕北地区生态系统整体呈现向好趋势，但部分区域仍需因地制宜地缓解水资源短板，提高食物供给能力，促进生产与生态的协调发展。
