In the coastal lowlands of the temperate and tropical zones , massive population displacements will occur due to rising sea levels and land shrinkage 温带热带的沿海低洼地区将有大量人口因海平面上升陆地减少而流离失所。
Coral and mangroves that follow the coast growth are the markings of the tropical zones coast , having the important research meaning and traveling worth 沿海岸生长的珊瑚和红树林是热带海岸的标志，具有重要的科研意义和旅游价值。
China lies east to pacific ocean and includes tropical zone , subtropical zone and mid - latitude zone . continent coastal dimate is variable 我国濒临太平洋，跨越热带、亚热带和温带三个气候带，大陆沿海及近海区域天气和海洋现象复杂多变。
4 ) the cochineal can finish life cycle under tropical , south sub - tropical and mid sub - tropical zones , but the cultivated female adults of these zones are much more different 结合胭脂虫的寄主仙人掌的生长状况，认为南亚热带区域为胭脂虫的最适生区，中亚热带区域为次适生区，而热带为适生区。
However , because of australia s vast size , there are variations within these zones . the temperate regions have all four seasons , while those in the tropical zone have two ( summer " wet " and winter " dry " ) 澳洲大陆古老而又美丽，她不仅拥有美丽迷人的黄金海岸、珊瑚礁和丰富的海洋生命，还有热带雨林、雪山、广阔的平原和一望无际的沙漠。
Natural geography condition in yunnan is superior , the mountain is high and water is long , the volume of rain is abundant , rich soil , and have the tropical zone , subtropics , temperate zone , the frigid zone weather 云南自然地理条件优越，山高水长，雨量充沛，土壤肥沃，兼有热带亚热带温带寒带气候。各种时鲜水果，品种繁多，四季不断，昆明街头常年都有供应。
The experiments of the optimal number of the cochineal female adults for propagation and cultivating the insect in the room and under shade in tropical zones are carried out to explore the laying number of the female adults and the cultivating methods in tropical zones 开展胭脂虫的室内放虫量及热带室内和遮荫实验等研究，探索胭脂虫的放虫量及热带胭脂虫培育的方法。
According to the report , global warming will lead to increased agricultural yield in the northern region of the temperate zone , but will be detrimental to farms in the tropical zone . this will further widen the gap between the rich in the prosperous industrial countries and poor in developing nations 报告指出，全球暖化将使温带北部地区农产增加，但却危害热带农业，进一步扩大工业化富国与贫穷的开发中国家间的贫富差距。
Through cultivating the cochineal in 4 counties which belonging to tropical , south sub - tropical and mid sub - tropical zones , the life tables of the cochineal in each county are established and the survival percentage of each stage as well as the key factor of death in each climate type is studied . in the meantime , the sample of the cochineal of each county is collected to test the size , eggs and weight , through comparing these biological index , the best zones , better zones and other zones for cultivation of the cochineal are pointed out . on the basis of above study , the zones for cultivating the cochineal are marked out in yunnan province 在云南热带、南亚热带、中亚热带三个气候类型下的4个县(市)放养胭脂虫，应用生命表技术，研究各气候类型下胭脂虫的存活情况并分析出各气候类型下胭脂虫的主要致死因子，同时，采集各地培育的胭脂虫样品测定虫体大小、怀卵量及重量，通过比较这些生物学指标，得出胭脂虫的最适生区、次适生区及适生区，并以此为依据，对云南省胭脂虫的培育进行了区划。
While under tropical zones , the size of the adults is the smallest , the eggs is the least and weight is the lightest , according to the results of statistical analysis , the female adults have distinct difference with adults cultivated under south sub - tropical and mid sub - tropical zones . the cochineal female ad 6 )在热带区域室内培育的胭脂虫虫体与亚热带区域培育的胭脂虫接近，另外，仙人掌在热带生长最快，结合这两方面的情况，热带区域虽然不适宜野外培育胭脂虫，但可将仙人掌茎片取回室内进行培育。
