应用人工神经网络BP模型预测乌江流域年平均含沙量

Application of Neural Network BP Model in Forecasting Yearly Average Sediment Concentration in the Wujiang River Basin

乌江流域溶解无机氮含量较世界平均水平高，其主要存在形式为硝态氮（NO3-N）。

The dissolved nitrogen ( DIN ) concentrations in the Wujiang River basin were much higher than the global average values and the main form of nitrogen was nitrate nitrogen ( NO3-N ) .

测量了喀斯特地区乌江、沅江两大水系的河流枯水期的主元素、Sr2+离子浓度和Sr同位素比值。

Major ions and Sr ~ ( 2 + ) concentrations and Sr isotopic compositions of two major river systems were measured in Guizhou karst region .

长江与其支流赣江、乌江的DSi年输送量与DSi年均含量和年径流量有密切关系。

Annual DSi transport is closely related to DSi annual content and annual runoff in Yangtze River and its tributaries of Ganjiang and Wujiang .

赣江流域与乌江流域DSi浓度年内变化规律相似，DSi浓度年内变化均较大，且DSi与水温呈显著正相关，DSi与DO呈显著负相关。

There are similar notable seasonal variations of DSi in Ganjiang Watershed and Wujiang Watershed , DSi and water temperature are significantly correlated , but DSi and DO are negatively correlated .

本文在利用MSS卫片影像编制贵州植被类型和乌江流域植被类型图的基础上，就贵州岩溶植被类型的卫片影像特征、解译方法及分布作一些初步探讨。

The paper discusses preliminarily the features and interpretation method of satellite photographic image and distribution of karst vegetation in Guizhou , based on the maps of vegetation types of Guizhou and Wujiang river valley , compiled from satellite MSS image .

结果表明：（1）乌江流域石灰土中REE的富集程度显著高于各自母岩、黄壤、上陆壳（UCC）、中国土壤（CS）和世界土壤（WS）；

The results show that the enrichment degree of REE in calcareous soils from the Wujiang catchments is much higher than that of limestone , yellow soil , upper continental crust ( UCC ), China soil ( CS ) and world soil ( WS ) .
