A study on the early-warning technique concerning debris flow disasters

According to the principle of the eruption of debris flows, the new torrent classification techniques are brought forward. The torrent there can be divided into 4 types such as the debris flow torrent with high destructive strength, the debris flow torrent, high sand-carrying capacity flush flood torrent and common flush flood by the techniques. In this paper, the classification indices system and the quantitative rating methods are presented. Based on torrent classification, debris flow torrent hazard zone mapping techniques by which the debris flow disaster early-warning object can be ascertained accurately are identified. The key techniques of building the debris flow disaster neural network (NN)real time forecasting model are given detailed explanations in this paper, including the determination of neural node at the input layer, the output layer and the implicit layer, the construction of knowledge source and the initial weight value and so on. With this technique, the debris flow disaster real-time forecasting neural network model is built according to the rainfall features of the historical debris flow disasters, which includes multiple rain factors such as rainfall of the disaster day, the rainfall of 15 days before the disaster day, the maximal rate of rainfall in one hour and ten minutes. It can forecast the probability, critical rainfall of eruption of the debris flows, through the real-time rainfall monitoring or weather forecasting. Based on the torrent classification and hazard zone mapping, combined with rainfall monitoring in the rainy season and real-time forecasting models, the debris flow disaster early-warning system is built. In this system, the GIS technique, the advanced international software and hardware are applied, which makes the system′s performance steady with good expansibility. The system is a visual information system that serves management and decision-making, which can facilitate timely inspect of the variation of the torrent type and hazardous zone, the torrent management, the early-warning of disasters and the disaster reduction and prevention.

两湖平原农业洪害特征与减灾技术措施

两湖平原是我国农业水资源最丰富的地区之一，河湖水系四通八达，农业生产条件优越。由于人类不适当的经济活动，大规模围湖垦殖破坏了两湖平原自然生态环境，洪涝频繁发生，农业损失严重。两湖平原必须实施综合性的农业减灾技术措施：长江上中游地区实施退耕还林、全面启动天然林保护工程，保持水土；两湖地区实行退田还湖，提高湖泊分蓄洪能力；应用GPS、GIS技术预警，有效调度洪水；调整湖区农业结构，发展避洪农业。     

西藏地质环境问题及保护对策

作为青藏高原主体的西藏自治区,地质环境极为复杂,地质灾害相当严重,在一些地段地质灾害严重影响了人们正常的生产生活。因此,加强地质环境保护,为人们创造尽可能好的生产和生活空间,是各级政府义不容辞的责任。本文首先对西藏自治区的地质环境特征作了系统地分析,并对西藏地质环境保护及管理现状作了客观评述,在此基础上指出了西藏地质环境保护中存在的主要问题。最后提出了西藏地质环境保护的对策及建议。     

试述福建顺昌南舟萤石矿地质特征

顺昌南舟萤石矿位于顺昌县埔上镇南舟村境内，1996年福建省区域地质调查队开展1：5万埔上幅区调时发现矿体，后开展普查工作表明该矿床规模大、交通方便，易于开采，现已投入开发利用。南舟萤石矿成矿地质特征在闽北丰富的萤石资源中具有一定代表性。     

遵义市城区及周边地带制砖页(泥)岩地质特征和开发前景

文章对遵义市城区及周边地带各地质时代的页（泥）岩已有资料进行了系统收集、归纳和适当的野外调研，认为区内制砖页（泥）岩层位可分为三类，第一、二类利用价值小或仅有部分可以利用，第三类则易于露采，大部分可利用，其层位为下奥陶统湄潭组和下三叠统夜郎组九级滩段，是区内可作制砖页（泥）岩利用最有开发前景的层位。同时对页（泥）岩的形成沉积环境作了简要分析，对其资源量进行了概略估算，经优化筛选，提出了10个供制砖厂企设置布局和矿源地选择之前需进行地质勘查的区块。     

六枝煤矿区构造体系初步分析

六枝煤矿区属于威宁—郎岱褶皱束的一部分，NW向构造占据主要地位。地史上该区有多次升降运动，二叠纪的东吴运动，伴随基性岩浆活动；侏罗、白垩纪的燕山运动，使本区发生大规模的褶皱和断裂；喜马拉雅运动的影响使本区构造复杂化。形成NE向扭性断层；构造复合的基本方式是横跨和限制。构造分析表明，NE向构造形成较早，NW向构造形成较晚。
