摘    要:考虑了水热条件的时空差异性,用净初级生产力对传统生态承载力模型进行了改进,并针对传统生态足迹模型中水生态帐户仅考虑渔业功能的不足,增加了水资源生态足迹的计算,最后用改进的生态足迹模型对1996—2003年间东营市生态足迹动态进行了分析.结果表明:1996—2003年间,传统模型计算的东营市人均生态足迹由1.766 hm2增至2.644 hm2,人均生态承载力由0.889 hm2降至0.813 hm2;改进模型计算的东营市人均生态足迹则由2.819 hm2增至3.776 hm2,人均生态承载力由1.935 hm2降至1.865 hm2;与传统模型相比,改进的生态足迹模型计算的研究区生态压力较小.加大对水资源的利用可缓解区域的生态压力,改进模型能更准确地反映研究区自然资源利用状况.

关 键 词:生态足迹  水热条件  净初级生产力  水资源  东营市

Abstract:Taking the spatiotemporal heterogeneity of water-heat condition into consideration, the traditional ecological footprint (EF) model was modified with net primary productivity (NPP). In the meanwhile, water resource EF was calculated to complement the deficiency of water EF account which only included water's fishing function. The EF dynamics of Dongying City from 1996 to 2003 was analyzed by using the modified model. Based on traditional model, the EF of Dongying City in 1996-2003 increased from 1.766 hm2 to 2.644 hm2, and the ecological capacity (EC) decreased from 0.889 hm2 to 0.813 hm2; while based on the modified model, the EF increased from 2.819 hm2 to 3.776 hm2, and the EC decreased from 1.935 hm2 to 1.865 hm2. Comparing with that from traditional model, the ecological pressure calculated by the modified model was lesser, which suggested that to increase the utilization of water resource would alleviate the ecological pressure on the region. The modified EF model was more precise to reflect the natural resource utilization of Dongying City.
Keywords:ecological footprint  water-heat condition  NPP  water resource  Dongying City
