Study on Population Carrying Capacity in Liaoning Province
摘要
Abstract
Rapid growing population and environmental issues have been key problems for the living and sustainable of human. Population carrying capacity is an important index for the regional ecological carrying capacity. Based on the meteorological data (with the resolution of 10 km × 10 km)in Liaoning Province from 1997 to 2006,the productivity (farmland,grassland and wetland) and its dynamics were calculated by using natural vegetation NPP model and agricultural productivity model. It was pointed out that the annual mean temperature showed a slightly decrease trend and the precipitation showed an increase trend. Total mean annual NPP of vegetation (farmland, grassland and wetland) in Liaoning Province from 1997 to 2006 was 3.63 × 10~7 t/a, and that of farmland, grassland and wetland was 2. 18 ×10~7, 0.99× 10~7 and 0.46 ×10~7 t/a respectively. Using the population carrying capacity model, total mean annual population carrying capacities in Liaoning Province from 1997 to 2006 under the consumption levels of well-off, comparatively well-off and surplus consumption were 2 226.9,2 035. 3 and 2 015.1 ten thousand people respectively.关键词
