查询词典 vegetation

We found 110 Kentish Plover nests in 8 sites, total area 22.74 ha, in Shengshi, Changhua during mid-April to mid-May. The hatching success of 89.09% was high compared to other studies. Thirty-six experimental artificial nests were set for a two weeks period in May to examine the effects of predators and rainfall. Among the 12 unsuccessful nests, 6 were flooded, 4 were abandoned, and 2 were predated. Successful nests and unsuccessful nests showed no difference in distance to nearest road and distance to nearest vegetation line.

调查从四月中旬至五月中旬於样区共追踪110巢东方环颈鴴的孵化情形，并於五月份设置36个人工试验巢进行两星期的追踪以了解捕食和降雨对孵化成功率的影响程度。110巢东方环颈中有98巢成功孵化，孵化成功率高达89.09%，以Mayfield Method 估算之孵化成功率亦高达83.53%，未孵化的12巢中，有6巢是因降雨淹水而失败，4巢是亲鸟弃巢，2巢被捕食。

The research carried out an experiment of extracting water from inland limnetic wetlands using TM remote sensing imagery based on many arithmetic,and concluded that spectrum classification was the best among the area accuracy index,extraction accuracy index and visual effect index,the following was single band threshold and vegetation index method,however,multi-band relationship and water index method was the worst.

研究基于TM遥感影像，运用多种方法针对典型内陆淡水湿地的水体信息进行了提取实验，通过对实验结果的分析得出：在面积的准确性、提取的准确度以及视觉效果3种指标下，光谱分类法较其它方法效果要好，其次为单波段阈值分析法与植被指数法，较差的是多波段谱间关系法与水体指数法；影响提取效果的主要原因是湿地水体提取不够完全，这是由影像的分辨率及湿地特殊的水文条件所造成的，采用像元分解及多源遥感数据融合技术将成为提高水体提取精度的重要手段。

Compared with lower-elevation vegetation types, higher ones were found significantly higher in their LOC content and proportion.

高海拔植被类型具有较高的土壤活性有机碳含量和分配比例。

A certain given low-temperature is necessary for the transition from vegetation growth to reproduction growth; a relatively high temperature is good for the formation of floral organ and floral stalk. The vernalized plants can finish the development stages of floral organ and floral stalk, no matter long-day or short-day.

其生殖生长过程包括了花器发育和花茎发育两个相对独立的生理过程；一定量的低温（7～8℃，26d）是诱导花器和花茎分化的必要条件，而较高的温度（17℃左右）对花器和花茎的形成均为有利。

Once lushly forested, Madagascar has seen more than 80% of its original vegetation cut down or burned since humans arrived at least 1,500 years ago, fragmenting habitats and leaving animals effectively homeless.

马达加斯加岛曾经林木繁茂，但自从一千五百多年前人类踏足岛上以来，已经有80%以上的原始植被遭到砍伐或焚毁，栖息地变得支离破碎，动物们实际已无家可归。
