The results are as follows:The relationship between the precipitation and the stemflow is a linear regression. The stemflow of six forest types is Broadleaf forest, Conifer and broadleaf forest, Cupressus funebris forest, Mixed conifer forest, Pinus massoniana forest and Shrubbery and grass land in order.
结果如下:树干茎流量与降雨量成线性相关,回归方程达到极显著水平;6种森林类型的树干茎流量从大到小依次为阔叶林、针阔混交林、柏木林、针叶混交林、马尾松林和灌草地;不同树种间的树干茎流量差异极显著,影响树干茎流量的主要树体特征因子是冠型结构、胸径和平均冠幅。

Consequently, to evaluate forest sustainability of a certain region becomes important in sustainable forestry and sustainable development. Forest carrying capacity is an important and key index in evaluating forest sustainability, premise of forest management and decision-making, and an essential component of the theories in sustainable forestry and forest management and forest ecosystem.
因此,如何评价一个确定区域的森林是否可持续便成为可持续林业、可持续发展研究中亟待解决的重要问题,而森林承载力是森林可持续性评价中的一个重要的关键的指标,是制定和实施区域可持续林业发展规划、战略的前提,是区域森林经营管理决策的依据,同时它也是可持续林业理论的重要组成部分,是森林经营管理理论和森林生态学中的一个全新内容。

The result indicates that the water, tundra, residential sites, needle-leaved forest and brass were decreased from 1977 to 1985; while the plantation and the coniferous and broad-leaved mixed forest obviously increased; and the broad- leaved forest, betula ermanil forest, road and bare soil also increased. During 1985 to 1999, the water, bare soil, coniferous and broad-leaved mixed forest, broad-leaved forest reduced, the rest landscape types increased in this area.
分析表明:从景观面积变化率来看,1977~1985年间,水体、苔原、居民点、针叶林和草地的面积减少,耕地和针阔混交林的面积增加显著,阔叶林、岳桦林、道路、裸地增加;1985~1999年间,水体、裸地、针阔混交林和阔叶林的面积减少,其他类型面积增加。

The four models were analyzed and normalized. We studied the procedure and method of building forest fire model base. Model base was build by object-oriented method based on category of model. Forest fire spreading models algorithm were implemented. We designed model dictionary base, model file base, and model knowledge base. Model base administration and maintenance functions were developed and implemented model file management, parameter management and knowledge management. The problems of interface between of model base and database were solved by means of model data control files. Model base ensured the availability of supporting for forest fire model suitability selection technology and forest fire model self-adapting updating technology.(3) Based on BP artificial neural network, we designed a frame construction of forest fire model selection of suitability. Forest fire model selection knowledge was produced through BP artificial neural network.
2建立了林火模型库建设的林火蔓延模型评价标准,根据模型评价标准和试验区实际情况,在42个林火蔓延模型中选择了目前最具有影响力和最具有典型代表性的Rothermel模型、王正非模型、加拿大模型和澳大利亚模型进行了解析和归一化处理;对林火模型库的建库过程和方法进行了研究,在林火模型分类基础上,采用面向对象的模型库表示方法建立了林火模型库;实现了林火蔓延模型算法,设计了模型字典库、模型文件库和模型知识库;开发了模型库管理与维护功能,实现了模型的文件管理、参数管理和知识管理;通过模型数据管理文件解决了模型库与数据库之间接口问题;实现了林火模型库对林火模型适宜性选择和林火模型自适应修正技术的有效支持。

The results showed that 9 natural vegetation types were distributed in 6 gradients. Except gradientⅠ, the dominant vegetation types along other gradients were all monsoon evergreen broadleaved forest. Gradient had greater effects on the distribution of seasonal rainforest and temperate coniferous forest, had some effects on the distribution of mountain rainforest, deciduous monsoon threat and river valley savanna forest, had smaller effects on monsoon evergreen broadleaved forest had no effect on warm-hot savanna forest and tropical bamboo forest.
结果表明:9个自然植被类型在6个坡度级均有分布;6个坡度级中除Ⅰ坡度级优势类型是水域外其他坡度级的优势植被类型均是季风常绿阔叶林;坡度对季节雨林和暖温性针叶林的分布影响较大,对山地雨林、落叶季雨林和河谷稀树灌木草丛的分布有一定影响,对季风常绿阔叶林和暖热性稀树灌木草丛的分布影响较小,对暖热性针叶林和热性竹林的分布无影响。

For the slope protection,domestic and foreign have various methods,such as:clean surface, and shotcrete stone surface and the use of concrete,asphalt,riprap,etc.,but these have a fatal weakness,the use of clean face,and shotcrete stone surface and the use of concrete,asphalt,riprap protection methods such as the slope,often due to excessive destruction of the human impact of the original natural and ecological environment.so that the entire road is almost formed a gray line,and While these protective measures outside the slope formed a protective layer of solid layer,but if there is a protective layer of water into the lower water flow and form,these protective measures will also be destroyed.
对于边坡的防护,国内、国外均有多种方法,比如:抹面、喷浆、石砌护面以及利用混凝土、沥青、抛石等等,但这些都有着致命的弱点,利用抹面、喷浆、石砌护面以及利用混凝土、沥青、抛石等方法进行防护的边坡,往往由于过多的人为影响破坏了原来的自然生态环境,使整条公路几乎形成一条灰色的路线,同时,这些防护措施虽然在边坡外面形成了一层坚固的防护层,但只要有水渗入防护层下部并形成水流时,这些防护措施也将被冲毁。
