用地。英文翻譯為

Should be "third type land for industrial usage".

But foreigners will never understand. You need toadd remarks to explain the areas it is different from the first and second types of land...Translation is very difficult. Another example is "十一五計畫". But use " National Plan 2006 - 2010" instead of "the Eleventh Five - year Plan".
