Translation of "primary productivity" into Chinese

Hotspots for primary productivity are necessarily also hotspots for production of oxygen as a direct result of photosynthesis.

初级生产力的热点必然也是氧气生产的热点,因后者是光合作用的直接结果。

It is understood that “rural” is no longer seen as just primary production.

现在“农村”已不再被理解成只从事初级生产。
