查询词典 savanna forest

The paper supposed five different land use scenarios, scenario1: most of the land use is forest and grass, scenarios 2: most of the land use is forest, sparsely forest and grassland, scenarios 3: the real land use of the region of interest, scenarios 4: most of the land use is range grass, sparsely forest and grassland, and scenarios 5: most of the land use is range grass.

本文假设了5种不同情景下的土地利用类型，分别设置为5种不同的情景：情景1为林地和草地为主的土地利用类型，情景2为林地、疏林地和草地为主的土地利用类型，情景3为研究区现有土地利用情况，情景4为裸岩、疏林地和草地为主的土地利用类型，情景5为裸岩为主的，少量草地的土地利用类型，其中5种情景类型中的水域量始终保持不变。

Cunninghamia Lanceolata showed that,after Cunninghamia Lanceolata sprout forest had been changed into Schima superba and Cunninghamia Lanceolata mixing forest,tree growth had largely been increased,and the water holding and conserving ability had been upgrated,as well as,the microclimate within forest had been improved,the forest land productivity had been protected.

木荷与杉木萌芽林混交试验，结果表明：杉木萌芽林改造为木荷杉木混交林后，林木生长量大幅度提高，林木和林地持水、保水能力增强，林内小气候得到改善，林分水源涵养能力进一步提高，林地生产力得到维护，为今后杉木多代萌芽林和杉木低产林改造提供科学依据。

Although forest canopy layer could prevent splash erosion effectively, clay was taken away by overland flow and run off easily, the erosion amount became less after removing the forest canopy and surface soil, while the splash erosion still produced in the surface layer; the splash function weakened after having water current, the starting particles were less than bareland, so removing the surface disturbed soil made the erosion amount and clay less, silty sand more than bareland, but unsteady, the wear and tear energy used by raindrop splash and current function for overcoming sediments separating and starting were comparatively large, sediments were very difficult to be started and transported, it explained that forest root systems could increase anti-erosion capability of forest vegetation, make rainfall-current system splash and export finer particles than bareland.

虽然林冠层能有效防止溅蚀的发生，但坡面流还是能带走粘粒部分，粘粒还是容易流失。去除林冠和表层土后，侵蚀量变得更少，但表层还是会被溅蚀，有水流后，溅蚀作用减弱，颗粒起动的比裸地的少，所以，去除表层扰动土后，侵蚀量更少，粉沙多，粘粒比裸地更少一些，但不稳定，雨滴击溅和水流作用用于克服泥沙分离起动损耗的能量较大，很难被起动输移，这说明森林植被根系的作用增加了林地植被的抗蚀力，使降雨一水流系统仅能溅起输出比裸地坡面更细小的泥沙颗粒。

Many tree species at the same time and solve the spatial heterogeneity which empirical method could not achieve. Therefore, the assessment method could be applied in the selection of species for afforestation or species selection in the forest restoration areas.From collecting the attributes of planting species, spatial distribution data and environmental factors, we could integrate and analyze the data for further simulating the forest dynamics of forest in Taiwan. The impact of global change on forest also could be evaluated.

应用生育地因子评估树种之生态地位，能解决统计实证方法在空间异质性使用的限制，并可同时评估多种树种，因此可应用在造林树种之选择，亦可应用於崩塌地复育造林树种之选择，以及林相改良造林树种之选择，在收集更多树种属性与空间分布资料后，配合此评估方法，未来更可模拟出台湾森林之动态，以及评估环境变迁对台湾森林所造成的影响。

It is shown that it is difficulty to differentiate each vegetation type among sub-tropical evergreen forest, sub-tropical coniferous forest and sub-tropical deciduous forest because of the mixture of their tree spectra. According to the reflection index in the wavelengths of 750 nm to 1 100 nm, the tree species can be divided into 4 groups with descend in reflectivity. Each tree specie can be differentiated from each other according to its slope of the spectrum curve and its reflection index in the wavelengths of 770 nm to 1 010 nm for each forest vegetation type. The unique first order derivative feature can be used to identify litsea, alder, fir, red birch, southwest birch, large schima confertiflora, taiwania flousian and small leaf schima confertiflora.

研究表明：亚热带常绿阔叶林、亚热带针叶林和亚热带落叶阔叶林等植被类型，因其树种间光谱特征混淆严重，而难以彼此区分；根据其反射率在750~1 100 nm范围上的差异，可将其归为4类；就各植被类型而言，其树种间在光谱曲线坡度，以及在770~1 010 nm范围上具有显著差异，可据此将其区分；木姜子、桤木、杉木、红桦、大叶木荷、秃杉和小叶木荷等因具有独特的光谱一阶导数特征，据此可以识别提取。

The maximum rate of decomposition of soil organic carbon insubtropical wetness area is red soil under coniferous and broad-leaved mixed forest＞yellowsoil under grass＞yellow soil under shrub＞yellow soil under broad-leaved forest＞red soilunder camellia oleifera; decomposition rate of yellow soil is faster than red soil. Themaximum rate of decomposition of soil organic carbon in subtropical wetness zone isyellow-brown soil under mixed forest in Nanjing＞red soil under adult fir in Yujiang＞redsoil under broad-leaved forest in Yujiang.

湿润亚热带地区森林土壤有机碳分解速率最大值出现在培养初期的一周内，其顺序：针阔混交林红壤＞茅草黄壤＞灌木林黄壤＞常绿阔叶林黄壤＞油茶红壤，同一植被下黄壤有机碳分解速率大于红壤，南京混交林黄棕壤＞余江杉木(32年)红壤＞余江常绿阔叶林红壤。
