| 1. | Outside hong kong , it is threatened by destruction of habitats and timber extraction 因生境破坏和人为砍伐,在中国的分布面积缩小。 |
| 2. | From ecotone between agriculture and animal husbandry distribution , the cover area in north is more th an south " 从分布的地区,我国农牧交错带在北方的分布面积要远远的大于我国的南方。 |
| 3. | By using these models , wetland landscape pattern and change along the yellow river in henan province in 1987 and 2002 are analyzed 第八部分为结论。结果表明: ( 1 )豫境沿黄湿地的分布面积呈下降趋势。 |
| 4. | The cause is that there are large distribution areas of moistly soil , wetly lands , and vegetative land , and smaller area of snow on the plateau 高原反照率年变化的主要原因是土壤含水量、雪盖分布面积及植被覆盖度的变化。 |
| 5. | Local people think that logging has less influences on the forest because the stumps will geminate again and for some years the forest will be back 这种寒温山地硬叶常绿栎类林虽然在流域内分布面积较广,但是也容易为当地人利用。 |
| 6. | On the contrary , " bare ground / city " has the highest heterogeneity degree because of its lung patch distance , more disintegration and better comparability “亚热带常绿、落叶阔叶混交林”分布面积最小,分化程度最弱,异质性最低。 |
| 7. | The existing experimental results show that malus toringoides distributed widely in different area which has great altitude variation and complicated microhabitats 现有研究表明,变叶海棠分布面积较广,海拔高度差异较大,微生境极其复杂多样。 |
| 8. | The frozen damage of slab - foundation of channel irrigation structures in the northeast of china is the most serious and includes the general characteristics of frozen damage of the channel irrigation structures 我国冻土分布面积极为广阔,虽然东北地区渠系水工建筑物的板基冻害最为严重,但也是其它地区的共性问题。 |
| 9. | The loess widely distributes in many parts of our country . as the loess has a lot of special construction properties , there are many highway diseases frequently - occurring in these areas , which is hard to guard against 黄土在我国的分布面积很广,由于黄土具有很多特殊的工程性质,导致这一地区公路病害频繁发生,防不胜防。 |
| 10. | Collapsible loess is one of the most widely ranged zonal soils in our country . it covers nearly 60 % of the total area of loess in china , which mainly distributes in the middle and downstream of yellow river 我国湿陷性黄土的分布面积约占黄土分布总面积的60左右,大部分分布在黄河中游地区,是我国一种主要的,分布较广的区域性土。 |
