产水量最终结果表格无空值,但栅格图层存在缺失值,是什么原因导致的?

Hello @fan8888 -

Unfortunately I don’t read Chinese, but here is a translator app’s translation of your question:
“There are no null values ​​in the final result table of water production, but there are missing values ​​in the raster layer. What is the reason?”

I’ll answer in English, assuming that you’ll also use a translator app.

First, I’m not sure how to interpret the map. What does “wyield_2000_RasterDomain” indicate? It would be easier to see the null values if you make them a different color.

Do the null values in water yield correspond to null values in any of your input layers? For example, soil data often has pixels with missing data/null values where there are water bodies, glaciers etc. Anywhere there are null values in your input data there will be null values in the output layers.
