| Abstract: |
| Analysing the space-time distribution characters of natural resources of high yield areas in Gansu,the results indicated that:the areas are generally abundant in natural resources;thermal resource is on the low side and have significant difference in vertical and level distribution;water resource lessness is the main restrictive factor;land nutrient quality is on the low side generaly also.Photophos potency accessed 16 468.5 kg/hm2 in Hexi area,taking the first place,Longnan and Longdong take second place,Longzhong lower than all others;photosynthesis-templerature potency accessed 10452.0 kg/hm2 in Hexi section,Longnan is 7 671.0 kg/hm2. |
