The main results are: construction of Tarim desert highway shelter-forest promoted soil microbial development, and with increase of plantation time of the shelter-forest, the quantity, fatty acid diversity index of soil microbe and diversity index of bacterial DNA segment enhanced notably. As to soil microbial community structure, bacteria are dominant population with amounting for over 80% of total soil microbe, and fungi is not more than 1% of total soil microbe, but soil microbial community structure was different among three soil layers. The conclusions from study methods of conventional culture, biological marker and molecule biology were almost identical, which illuminates that construction of Tarim desert highway made soil microbial activity enhance and so promote nutrient cycle and utilization of Tarim desert highway shelter-forest land.
结果表明,塔里木沙漠公路防护林的建设促进了风沙土土壤微生物的发育,随着防护林定植年限的增加,土壤微生物数量、脂肪酸和细菌DNA片段的多样性指数明显增大;土壤微生物区系组成中,细菌是优势类群,占微生物总数80%以上,而真菌很少,不到微生物总数1%,但在不同土层间有所差异;传统培养法与现代生物标记和分子生物学方法对塔里木沙漠公路防护林地土壤微生物多样性的研究结果基本一致,说明塔里木沙漠公路防护林的建设使林地土壤生物活性有所增强,有利于林地土壤养分循环与利用。

Beijing is provided with typical urban landscape, forest land is the maximal and basal landscape patch type (area proportion 42.534%), glebe field (28.754%),spinney land and urban (26.912%) and town residential landuse (10.344%) are main landscape patch categories in Beijing. From landscape, landscape patch types and landscape patch categories levels, landscape patch distributing centralize, and patch shape is simple, main landscape patch fractal dimension indexes are under 1.1, so urban landscape pattern is high influenced by human disturbance.2. From 1985 to 2007, Beijing landscape pattern variational characteristics are as follows:(1) During 1985-2007, patch types and categories change is little, but area and patch number of patch types and categories change distinctly. Town residential landuse area increased 7.66% of Beijing total area, farmland and forest land area decrease in the mass. The total patch number increased at first then decreased. taking one with another, the total number is decreasing, and patch number of farmland and forest land are most distinct.
本研究的主要研究结果如下:1、北京市具有典型的城市景观特征,林地用地的面积占市域面积的42.534%,为基质景观斑块类型,旱田(28.754%)、灌木林(26.912%)、城镇用地(10.344%)是北京市主要景观斑块种类;从景观、景观斑块类型以及景观斑块三个层次的研究均表现出北京市各景观斑块类型及景观斑块集中分布的现象十分突出,斑块形状简单,主要景观斑块种类的景观分维度指数值均不足1.1,表明城市景观格局受到了较大的人为影响。2、北京市1985-2007年间城市景观格局的主要变化特征表现为以下几个方面:(1)在研究时段内,北京市景观斑块种类变化不大,景观组分面积和斑块数变化明显,其中最为显著的是北京市城镇建设用地面积呈单纯的增加趋势,增加幅度为北京市总面积的7.66%,农业用地与林地的面积虽呈波动变化但总体呈减少趋势;景观斑块数量先增后降,总体呈下降趋势,其中耕地与林地斑块数的变化最为明显。

The Forest fire prevention is the technology which has much relations with geographic information, so if we make use of 3S technology, we can greatly improve the levels in the area of monitoring, saving, forecast, analyze, statistic and decision so as to prevent in unfired state and discover at litter fire and save life and properties in time. Only by this way can we reduce the losses from forest fire disaster and protect the forest ecological resources and pepoles life and properties.
作为与地理信息密切相关的森林防火,采用3S技术,可以大为提高森林防火的监测、救援、预测、分析、统计、决策水平,从而防患于未燃,发现于小火,及时扑救,最大限度地减少森林火灾的损失,保护森林生态资源和人民生命财产安全。
