| 摘 要： | 随着人口的不断增加，资源、环境、人口与发展之间的矛盾日益突出，土地资源能否生产足够的食物供养未来人口的问题受到普遍关注。基于1997—2006年辽宁省10 km×10 km分辨率的气象资料，通过自然植被净第一性生产力模型和农业生产力模型计算了农田、草地和湿地的生产力及其动态。结果表明：近10 a来辽宁省年平均气温呈略下降趋势，年降水量呈增加趋势。1997—2006年辽宁省植被年平均总净第一性生产力为（农田、草地和湿地）3.63×107 t•yr-1，其中农田、草地和湿地分别为2.18×107 t•yr-1、0.99×107 t•yr-1和0.46×107 t•yr-1。应用人口承载力模型计算出在宽裕型、小康型和富裕型3种消费水平下1997—2006年辽宁省的年平均总人口承载力，分别为2226.9万人、2035.3万人和2015.1万人。

| Abstract: | With the rapid increase of population, the contradictions among resource, environment, population and economic development become more and more prominent, whether the land resource can produce enough food to support the future population is concerned. Based on 10 km×10 km spatial resolution meteorological data from 1997 to 2006 in Liaoning province, net primary productivity (NPP) and its dynamic changes of different ecosystems were simulated by NPP model and agricultural NPP model, including farmland, grassland and wetland ecosystems. The results indicate that mean air temperature in the recent decade decreases in Liaoning province, and annual precipitation increases. The mean annual NPP (including farmland, grassland and wetland ecosystems) from 1997 to 2006 is 3.63×107 t•yr-1. NPP of farmland, grassland and wetland ecosystems are 2.18×107 t•yr-1, 0.99×107 t•yr-1 and 0.46×107 t•yr-1. Under three consumption levels, i.e. an affluent life, a fairly comfortable life and a rich life, mean annual population carrying capacities from 1997 to 2006 are 22.269M, 20.353M and 20.151M in Liaoning province by the population carrying capacity model. |
