Gradient analysis and environmental interpretation of woody plant communities in the middle section of the northern slopes of qilian mountain , gansu , china 祁連山北坡中段森林植被梯度分析及環境解釋
The conclusion of ca was in accordance with the result of survey , so ca is a good tool for gradient analysis and ordination of unknown community 聚類結果與實際調查相符,由此說明ca方法能夠對未知群落進行較好的分類和排序。
Proceeding from this practical issue , with a gradient analysis of the mutual influence mechanism of sustainable development , this writer holds that the process of technology diffusion plays an innate stimulating role in sustainable development 文章指出,受到社會資本影響的技術擴散過程對可持續發展有著內生性的激勵作用。
3 eight communities are identified by gradient analysis in desert - oasis ecotone , and species are divided into 5 ecological groups . dca ordination is superior to cca and dcca . variation of vegetation explained by environmental and spatial factors reaches 23 . 4 % ; among these the species matrix explained by non - spatial soil factors account for up to 11 . 5 % of variation , spatial variation that is not shared by soil factors explains up to 11 . 6 % , their interaction explains up to 0 . 3 % 3 、通過梯度分析,阜康荒漠綠洲過渡帶群落可分為8個類型,物種可分成5個生態類型; dca排序效果優于cca和dcca ;土壤和空間因子解釋了植被分異的23 . 4 ,其中土壤因子占11 . 5 ,空間因子占11 . 6 ,二者交互作用占0 . 3 。
百科解釋
Gradient analysis is an empirical analytical method used in plant community ecology to relate the abundances of various species in a plant community to various environmental gradients by ordination or by weighted averaging. These gradients are usually variables that are important in plant species distributions, and include temperature, water availability, light, and soil nutrients, or their closely correlated surrogates.
