摘　　要：利用周广胜、张新时提出的自然植被净第一性生产力模型,估算分析了乌鲁木齐地区近30年自然植被净第一性生产力(NPP)的时空变化。结果表明,除后峡地区的NPP呈递减趋势外,其它各地的NPP总体上呈递增趋势;中山带的NPP最高,亚高山、高寒、低山和山前荒漠地带依次降低;气候变暖除对高寒地带的自然植被的NPP有一定的正效应外,对其它地区的NPP均产生较明显的负效应;年降水量的增加对提高自然植被净第一性生产力具有积极作用。Based on the natural vegetation NPP model Zhou Guangsheng and Zhang Xinshi, The space - time changing trend of natural vegetation NPP in Urumqi area in the last 30 years was estimated. Results showed that NPP Changing tendency was charaeterized by the progressive decrease in Houxia station, the progressive increase in the rest of stations, the maximum NPP in the middle of moutains, the progressive clecrease in the high mountain, low mountain, and foot of a mountain. Climate warming produced only a definite positive effect to NPP values of mountain - clod belt, it has negative effect for the rest of areas. Increasied annual precipitations have played a positive role to improve Natural vegetation NPP.
