The character and kinetic for the growth of microorganism were investigated in aerobic thermophilic composting process. It was considered that the growth of microorganism was affected largely by temperature. It showed wave change of microorganism growth along with temperature change. Meanwhile, a kinetic model of microorganism growth in the aerobic thermophilic composting was established based on Logistic model and Malthus model. The model was scientific according to its numerical simulation results being consistent with experiment results and rightly reflected the growth rule of microorganism in the aerobic thermophilic composting.

The purpose of the study is to contrib ute to land use planning through analysis of the characteristics and requirements of several population prediction models.Methods of statistics and comparison study were e m-ployed.Population prediction models were established based on historical demographical data and population was predicted periodically and compare d to actual values.By comparison and analysis of the residue errors,the characteristics and requirements o f each population prediction model w ere summarized.Mono-linear Regression model is suitable when the data have a pparent linear tendency.Index-smo oth model and Moving Average-data model are appropriate when historic al data are insufficient.GM(1,1)model can be selected when the data are complex.Population Natural-incre asing model and Malthus model can be u sed when the data are accurate while Songjian model is more precise in short-term prediction.The above models can be used comprehensively in land use planning.

研究目的:研究土地利用规划中几种常用人口预测模型的特点和适用条件,为土地利用总体规划编制工作服务。研究方法:统计分析法和对比分析法。研究结果:利用人口历史统计数据建立预测模型,分时段进行预测,并与实际观察值比较,得出预测误差的大小,通过预测误差大小的分析比较,总结了各种预测模型的特性与适用条件。研究结论:一元线性回归法适用于数据直线趋势较明显的预测;历史数据较少时,可用指数平滑和移动平均数法;数据情况复杂时可采用GM(1,1)模型法;自然增长率等资料准确可靠时可采用人口自然增长法或马尔萨斯法;宋健模型法用于短期预测的精度较高;土地规划中人口预测应多种预测方法综合运用。
