| 中文摘要: |
| 甘肃省高产农区农业自然环境资源时空组合特点及其光合潜力、光温潜力、光温水潜力和光温水土潜力的分布变化规律分析结果表明:甘肃省光能资源丰富;热量资源偏低且垂直和水平差异显著;水资源贫乏;土地质量普遍偏低。光合潜力河西区可达16 468.5 kg/hm2,陇南和陇东次之,陇中较其他各地差;光温潜力河西区为10 452.0 kg/hm2,陇南为7 671.0 kg/hm2,河西和陇中地区光热同步,光温潜力达光合潜力的66.62%和65.95%,陇东和陇南地区为57.49%和53.06%;在河西绿洲灌区,光温水潜力和光温水土潜力均最高,分别占光温潜力和光温水潜力的88.0%和95.7%以上;陇中、陇东和陇南区较低,光温水土潜力仅达光温水潜力的60%67.4%。 |
| 英文摘要: |
| 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. |
