- Geophysical characteristics , such as electric and magnetic parameters of strata ( rocks ) in longchuanjiang basin are analysed and discussed in this paper
摘要本文对龙川江盆地地层（岩石）电、磁性参数等地球物理特徵进行了分析与研究。 - This study uses quantitative remote sensing method on soil losses which based on 3s technique and supported by gis software to probe into the application of quantitative remote sensing method on soil losses . and according as the equations of soil losses ( a = fkrslcp ) & predicting soil conservation intensity ( y = cp - cp " ) to realize the 3s technique integration on gis platform in study area of longchuan river drainage basin
本研究采用基于3s技术的水土流失定量遥感方法，以gis软件为平台，以龙川江流域为试验区，依据水土流失方程( a = fkrslcp )和防治强度预报方程( y = cp - cp ' ) ，进行了在以3s技术为支撑的水土流失定量遥感方法的应用探索，实现了在gis平台上3s的集成。 - In the first place , the study processed data of remote sensing and non - remote sensing to be digital , vector , raster and imagery geocode , established geographic database of soil erosion , and calculated elements " pixel maps of soil erosion . secondly , by using model builder of arcview to establish dynamic survey model of soil losses in longchuan river drainage basin . at last , to obtain maps of status & the forecast maps for soil conservation
首先通过遥感与非遥感资料的数字化、矢栅化及图形图像地理配准，建立了水土流失地理数据库，并运算出水土流失各因子像元图；在此基础上，凭借arcview子模块modelbuilder的支撑，建立龙川江流域水土流失动态监测模型；最后运行该模型获取水土流失现状图和防治预报图等结果图件，完成了研究区1998 、 1999年水土流失定量遥感监测任务。 - Considering the influence of dynamical factor of sediment discharge as well as the difficulty of calculating number of input cell , the model is provided with strong nonlinear mapping capacity and applied to simulate and forecast monthly sediment discharge of longchuan river watershed , the outcome is reasonable with higher precision
模型既能考虑到影响输沙量时间序列的动力因子，又能解决网络的输入单元数确定的困难和利用神经网络超强的非线性映射功能，通过对龙川江流域控制站月输沙量的拟合与预测表明其结果合理，预测精度较高。
