| 1. | The diversity of soil parent material types , soil types and vegetation types are analyzed with the landscape ecology methods 采用景观生态学的原理与方法,对张掖市土壤母质、土壤、植被的景观多样性进行了研究。 |
| 2. | From the 3 landscape ecological system , the evenness of soil landscape system , soil parent material system and vegetation system are 65 . 12 , 53 . 50 , 40 . 0 . 5 在张掖市的3类景观系统中,景观均匀度最高为的土壤景观系统( e 65 |
| 3. | The total capacity of calcium & magnesium was much influenced by soil parent material . along with the soil development and forming process stronger , this influence was weaker 成土母质对于土壤基本理化性质的影响主要体现在土壤钙镁总量上,这种影响随土壤发育的成熟和发生过程的加强逐渐减弱。 |
| 4. | The total number of patches is 90 , among which the soil parent material type is 28 , the soil type is 46 and vegetation type is 16 . there is a different changing trend among the patch number and maximum landscape diversity , landscape diversity and number of type elements 土壤母质景观系统、土壤景观系统、植被景观系统分别包括28 、 46 、 16个斑块。斑块数量( np )的变化趋势与最大景观多样性指数( hm 。 ) 、景观多样性指数(厂) 、景观组分类型数量( n |
| 5. | The vegetation landscape ecological system is made of 8 elements and has the lowest maximum landscape diversity ( h nax ^ . 9031 ) the soil landscape system is consisted of 11 elements ; the maximum landscape diversity is in the middle of soil parent material and vegetation system ( h max = l - 0414 ) 1461 ) :土壤景观系统由11种景观组分组成,其最大多样性指数居中(凤删i刀414 ) :植被景观系统由8种景观组分组成,其最大景观多样性指数最低( hidax 0 903 ) 。 |
| 6. | The data indicated that chemical and physical characters of soil in different vegetation types which in same climate type have some difference . that reflected chemical and physical characters of soil not only have relation with soil parent material , climate , physical chemical characters of chemical elements itself , but also with vegetation types 数据表明,在同一气候条件下,所覆盖植被类型不同,土壤理化性质也有差异,反映了土壤理化性质除了与其成土母岩、气候和化学元素自身物理化学性质有密切关系外,植被类型的作用不可忽视。 |
| 7. | Despite the same tpyes of soils in this region ( the majority is dry red soil ) , different types of soil parent materials / rocks imposed an important influence on soil infiltration due to soil degradation such as the removal of soil material and appearance of gravels / rock fragments . as a result , plant growth is closely related to the types of rocks 尽管该区不同的母质母岩发育形成相同的土壤一简育干润富铁土(过去称燥红土) ,但母质母岩特性却对植被生长有明显的影响,其主要原因是土层浅薄化、石质粗骨化使土壤受岩性特征深刻制约,导致不同土壤?母质?母岩系统表现出显著的渗透性差异。 |
| 8. | The vegetation type has the smallest maximum landscape diversity and landscape diversity , and suffer the biggest human being disturbuance . the soil parent material has the biggest maximum landscape diversity and landscape diversity , but human being have a little effect on soil parent material . compare with soil parent material and vegetation , the soil type have the mediate position 因为植被景观系统的最大景观多样性指数、景观多样性指数最小,但受到人类活动的干扰最大;土壤母质景观系统的最大景观多样性指数和景观多样性指数最大,但人类活动干扰强度最小:土壤景观系统的最大景观多样性指数和景观多样性指数、人类活动的影响都处于中间位置。 |
