As the basement to integrate multi-scale spatiotemporal data, the object evolution model can retain the characteristic of the data with different temporal-scale or different spatial-scale, and reflect the temporal changes especially the heteromorphic changes, and the causalities within the evolving process.

本文通过对时空对象变化过程的分析，指出对象进化的结果不仅是特征的变化，还包括机制的变化，其直接动力是对象行为，其根本原因是其内在机制，时空事件起着对象间信息通道的作用，据此提出对象进化模型，该模型可作为多尺度时空数据集成的结构性基础，在反映时空现象的演变过程，特别是异构演变过程，以及在这个过程中产生的因果关系的同时，还可以保留时空数据的不同时间尺度和空间尺度特点，从而达到增加时空数据库的信息量的目的。

Considering the difference of runoff characteristics on different underlying surface in the area of plain tidal river network, four kinds of surface is divided,namely, waters paddy field-, dry land and central urbanized area,and suitable method is adopted separately in each surface to simulate runoff process. Xinanjiang Model usually applicable for mountain areas is introduced to river network area, furthermore, the paper researches runoff calculation of central urbanized area, the underlying surface is divided into pervious and imperviousness areas.In perviousness areas, Hoton Infiltration formula and corresponding spatial infiltration rate curve are used to establish the relationship between infiltration rate and soil moisture in order to decide the infiltration. According to practical situation.

根据平原河网区城市下垫面产汇流方式的不同，分成水面、水田、旱地、城镇四类，分别采用相对应的产流汇流计算方法，将适用于山丘区的新安江模型引入到平原河网区城市，同时对于城镇这类下垫面，从下渗角度考虑，划分成透水和不透水两种类型，根据霍顿下渗公式和下渗率空间分布曲线，建立下渗率和土壤含水量的关系，进而研制出城镇透水面的产流计算方法，城镇汇流根据实际情况可结合城市管道排水计算。

For such reasons, the author investigated comprehensively on cropping systems and agriculture development in Fenxin County from 2002 to 2004, using mathematics model and GIS, discussed the cropping systems characteristic and development orientation and optimized the cropping systems spatial distribution. The data were collected from literature, questionnaires to experts and farm households, on-site investigation and field experiments. The main results are as follows:1,Because of inconsequent exploitation and management of the resources, rapid increasing population in hilly region of red soil, the stress on soil, deterioration of farmland ecological environment and soil gleization become more and more serious. Natural features , water and thermal resources and species are abundance.

基于以上目的，作者于2002-2004年，通过资料调研、专家咨询、农户调查、实地考察和田间试验等手段，对江西奉新县的种植制度和农业发展进行了全面的调查，通过建立数学模型和运用地理信息系统，对奉新县的种植制度的特征和发展方向进行了全面的论述，并且对种植制度进行了空间布局优化，主要结果如下： 1、红壤丘陵区由于长期以来对资源的不合理利用和掠夺式经营以及人口的急剧增长，土地压力上升，农田生态环境恶化，土壤潜育化，土壤肥力退化非常严重，但区内自然条件优越、水热资源总量丰富、物种丰富，具有一定的区位优势，为区内种植制度调整提供了有利条件。
