this paper makes the gas remote monitor network as background to do some research on the qos guarantee of the network.qos is a synthesis guide line which can be used to estimate the degree to satisfy with some server,which is a technology to solve the problem of delay and congestion in network.it must integrate multi-qos mechanism to get good qos guarantee in the practical application.three qos models in the ip net application and homologized affective factors are demonstrated.meanwhile,the field of qos protection strategy arrangement in shaanxi coal mine gas network has been picked up as the example.for this situation,the comparison to the different qos models is doing strictly.by combining the tcp congestion control arithmetic with ip congestion control arithmetic,the paper also emphatically describes the corresponded arithmetic model for that.stimulatingly,it is promoted the qos characteristic over-area effectively,which it is based on the original single congestion control.

摘 要：以陕西煤矿瓦斯监测远程联网为背景，研究其联网网络的qos保障策略实现。由于现有的各种qos实现机制无法单独为陕西煤矿瓦斯监测联网网络的qos提供保障，因此在实际应用中必须结合多种机制才能得到较好的qos保障效果。比较了传统ip网络的qos结构体系，通过分析intserv和diffserv两种模型的基本原理、工作方式，并指出其各自的优缺点和网络应用环境，设计了将rsvp协议与diffserv模型相结合来满足瓦斯监测数据传输实时性的要求；针对陕西煤矿瓦斯联网的特性，提出了将tcp拥塞控制算法与ip层拥塞控制算法相结合的算法模型，并且该模型的应用可以在原有单一拥塞控制的基础上有效地提升跨地区网络的qos特性。关键词：服务质量；综合服务模型；区分服务模型；拥塞控制

Pure-remote sensing information models are free of the numerous distributional parameters that are difficult to obtain in vast area. The following sections are included in the study.(1) The VCI and SVI based on time-series NDVI data are used to analyse regional drought and the following results were reached: As the vegetation growth status index, the response of VCI and SVI to precipitation was land cover type, temporal and site specified. So VCI and SVI have little information about drought when used to monitor regional drought especially in China that has a mountainous topographty.(2) Based on the interpretation of NDVI-Ts space, NDVI and land surface temperature was combined to construct NVDI-Ts space from which the TVDI (Temperature Vegetation Dryness Index) was obtained with line ratio method and normalized slopes method. When compared with the topsoil moisture measured in situ, TVDI are competent in regional drought monitoring. Illumed by the NDVI-Ts space, we combined the NDVI with day/night land surface temperature difference and apparent thermal inertia to construct NDVI-ΔT and NDVI-ATI spaces from which the DVDI and AVDI were estimated respectively with 8-day composite MODIS 〓 product and 16-day composite MODIS NDVI product.

具体包括以下几方面的内容：(1)VCI和SVI在干旱监测中的作用评价：探讨利用NDVI时间系列数据建立的植被状态指数和标准植被指数评价区域干旱的可行性，研究结果表明：VCI和SVI作为植被相对生长状况指标，对降水的响应随着植被覆盖类型、时间和空间等而表现出不同的敏感性，因此在大区域干旱监测中，特别是我国这样地形复杂多样的国家，VCI和SVI在干旱监测中的作用都是有限的；(2)利用TVDI评价全国干旱等级分布：结合陆地表面温度和植被指数建立NDVI-T〓空间，在NDVI-T〓空间物理意义理解的基础上，分别采用线段比值法和斜率归一化法构建温度植被干旱指数，并利用TVDI研究了我国2000年3～5月份各旬的干旱分布，取得比较满意的结果。

In order to solve the frost heave and thaw settlement, the model tests were made in Tibetan Plateau. Two kinds of model were designed to horizontal drain structure embankment and the ventilation embankment in suit. The effect of horizontal plastic drain was analyzed in contrast with the ventilation embankment. The mechanisms of horizontal plastic drain were studied in permafrost, such as gravity draining in the superficial layer and structure stiffing in the embankment in the theory. According to the design theory, the parameters of horizontal plastic drain were confirmed in the embankment. The values of deformation were inspected by fiber monitor system in the permafrost embankment.
