Its landscape pattern and structure of tree populations are adapting to its functions , which is faver to decrease the disturb from people 其不同類型綠地斑塊分布格局與樹(shù)種結(jié)構(gòu)分布與其各自功能相適應(yīng),有利于分散干擾危險(xiǎn)。
The result shows that the vast majority of the main tree populations in the ? castanopsis carlessii ? forest are of broad niche ; that the relation among the species is very complex ; and that many species share the same resources 采用定量分析方法,對(duì)武夷山米儲(chǔ)林群落12個(gè)主要種群生態(tài)位(包括生態(tài)位寬度、生態(tài)位相似性比例、生態(tài)位重疊)進(jìn)行了測(cè)定。
In this study , the niche characteristics of 12 main tree populations in ? castanopsis carlessii ? forest have been analyzed by quantitative method at the nature reserve of wuyi mountains , including niche breadth , niche proportional similarity and niche overlap 植物種群之間的生態(tài)位相似性比例和生態(tài)位重疊指數(shù)指標(biāo)值反映了亞熱帶常綠闊葉林的生態(tài)特征。
According to the prominence it was estimated that the corrlelation of different parameters of its landscape pattern and that of its populations structure , and then the result was deeply analyzed and the relation of its landscape pattern and the structure of tree populations and their mutual adaptability was deeply discussed 另外分別統(tǒng)計(jì)樹(shù)種結(jié)構(gòu)參數(shù)與景觀格局參數(shù)之間的pearson相關(guān)性系數(shù)與顯著性值,依據(jù)顯著性值分別判斷不同景觀格局參數(shù)與樹(shù)種結(jié)構(gòu)參數(shù)之間相關(guān)性程度,探討花港觀魚(yú)綠地景觀格局與其樹(shù)種結(jié)構(gòu)之間的關(guān)系及其相互適宜性。
It was quantified that the landscape pattern of the green space and its structure of tree populations in the huagangguanyu park , and the parameters of landscape pattern and tree populations structure of its green patches was calculated , and then their mutual pearson relative coefficient and prominence were counted too 對(duì)杭州花港觀魚(yú)公園綠地景觀格局及其樹(shù)種結(jié)構(gòu)分別進(jìn)行量化分析,計(jì)算出各種不同類型綠地斑塊的景觀格局參數(shù)與樹(shù)種結(jié)構(gòu)參數(shù),探討花港觀魚(yú)樹(shù)種結(jié)構(gòu)與景觀格局。
