| 6. | The moisture degree indicated that all the four forests were humid annually , but different monthly 年平均湿润度计算结果表明各林型均为湿润,但月湿润度差异明显。 |
| 7. | Bird reduction with the increasing of people activities , deforestation and hunting , however , the vicissitudes are difference in different types of forests 云南西双版纳地区原始森林面积逐渐减小,人口及人为活动不断增加,鸟种趋于减少,但各林型鸟种变化有异同。 |
| 8. | The capacity of the decrease of maximum air temperature in forests was the principal factor of decreasing the annual mean differences in daily range of temperature 这4种森林的年平均日较差依次为5 . 9 、 4 . 6 , 3 . 6和3 . 1 ,且月变异系数逐渐减小,森林主要通过降低日最高温而减少林型间气温日较差。 |
| 9. | The soil nutrient contents of total nitrogen , total phosphor us and total potassium were studied at the same time . and then , the probable correlations between the quantities of microorganisms and soil nutrient content were analyzed . the results suggested that soil water content decreased with the depth increasing , this value of soil water was the highest in plot g1 ( coniferous forest ) , because of the highest altitude 同一林型下不同土壤深度,养分全量差异显著,且随深度增加而显著减小,不同林型植被之间,全磷含量差异显著,全钾含量在高山柳灌丛( l _ 3 )与洗澡塘沟羊茅群落( l _ 4 )之间差异显著,说明植被类型的不同,对土壤养分全量也有一定的影响。 |
| 10. | By the study of metallogenic geologic characteristics of the various gold deposits , the author sets up the ore - forming model of some typical deposits such as shuangqishan deposit and zhijinshan deposit etc . . it is considered that the gold deposits of metamorphic rock category and the volcanic rock category are the main gold - prospecting categories and carlin gold deposit and mulongtao gold deposit are the potential categories in fujian province 系统总结了福建省各类型金矿的成矿地质特征,建立了双旗山金矿和紫金山铜金矿等典型矿床的成矿模式,提出了变质岩型金矿和火山岩型金矿是福建省金矿找矿的主攻类型,卡林型金矿和穆龙套式金矿为潜在找矿类型。 |
