一张植被图可以反映一个地区植物群落的状况，是做好保护和发展工作的一个基础。打好这个基础很 难，绘制一张小范围的植被图，都需要大团队做野外调查、反复验证。为青藏高原绘制植被图，难度更 超乎想象。 这超乎想象的难题，被我们团队攻克了。今年6月，我们发布《青藏高原草地植被群系图 （1∶500000）》。这张目前我国精度最高的青藏高原草地植被图，精细刻画了65种植物群系或群系组的 空间分布格局。 青藏高原是有草地植被图的，为何又要绘制？近几十年，青藏高原在变暖、变湿、变绿。具体绿在哪 里？是优质牧草还是杂草？之前的图无法给出准确答案。3.7万多个野外调查样点支撑的新图，为青藏 高原变暖、变湿的趋势提供植被地理学证据，进一步夯实了保护和发展的根基。 我们的图"新"在哪？不只在描绘新变化，绘图方法也新。传统的制图方法主要靠专家经验和一次次跑野 外。我们运用人工智能，通过深度学习技术训练出"植物识别专家"，将"铁脚板"带回的一手数据和卫星 获取的海量特征都"喂"给它，让它分析不同植物的群落特征、产草能力、生长节律等。"专家"速度快， 还能发现人眼很难发现的复杂规律。技术更新，为科研的与时俱进增添了新动能。 技术固然有益，但 ...
