In this paper, a multimodel approach for urban population-economy policy simulation is proposed. With the approach, the supply and the demand for urban labour population are calculated; when the supply is more than the demand, the mechanical growth population is calculated by means of the time sequence model; ortherwise, the balance model between the supply and the demand for labours is used. An example is presented and the results provide a more scientific basis for formulating the relevant policy.

本文提出城市人口-经济政策仿真的一种多模型方法:分别计算相应政策方案下城市劳力人口的拥有量和需求量,当拥有量大于需求量时采用时间序列模型计算机械增长人口,否则采用劳力人口平衡模型。文中给出了应用实例,其结果为制定有关政策提供了比较科学的依据。

This paper deals with age-structure and growth process of dominant species with importance value higher than 10 in Castanopsis carlesii community in Wuping Maobu. The results show that Castanopsis carlesii, Machilus pauhoi, Schima superba and Castanopsis fargesii belong to growth population,Cinnamo mum micranthum, Castanopsis fabri, Elaeocarpus chinensis and Daphniphyllum oldhamii belong to stable population, Cunninghamia lanceolata and Pinus massoniana belong to decline population.

This paper deals with age-structure and growth process of dominant species with importance value higher than 10 in Castanopsis carlesii community in Wuping Maobu. The results show that Castanopsis carlesii, Machilus pauhoi, Schima superba and Castanopsis fargesii belong to growth population,Cinnamo mum micranthum, Castanopsis fabri, Elaeocarpus chinensis and Daphniphyllum oldhamii belong to stable population, Cunninghamia lanceolata and Pinus massoniana belong to decline population. The time reaching the highest growth in height and diameter of Castanopsis carlesii occurs between the ages of 30 to 36 years,and 36 to 40 years respectively. The volume growth of Castanopsis carlesii speeded upat age of 26 years, but don't reach the highest increment before 40-year-old.

On Songnen grassland, we detendbed the above-gmund biomass of oneyear growth, two-year growth, three-year growth, six-year growth and wild growth population P. tenuiflora, and we have done the mathematical simulation with them. The logistic curve fits with the above - ground biomass of P. tenuiflora before ear spmuting pariod, but it didn't fit with the senacence procss of P.tenuiflora after the above -ground biomass bad reached the matximum biomass.

在松嫩盐碱草地上,我们对人工种植在碱斑土壤上生长一年、二年、三年、六年的星星草种群以及野生的天然星星草地中的星星草种群地上生物量的季节动态进行了测定,并进行数学拟合。用Logistic曲线拟合时,抽穗期以前拟合情况较好,但不能很好地拟令星星草种群达最大生物量后衰老的过程。用一元多次曲线则能很好地拟合星星草种群地上生物量随生育时间的季节动态。
