INFORMATION ABOUT BIOTOPE
关于生物群落的信息
Description of the area surrounding the biotope: Southern China is rainy and hot in summer, ponds are often seen near woods and grasslands. The pond is surrounded by dense vegetatio.
生物群落周边环境描述：中国南方夏季多雨且炎热，池塘常见于林地和草地附近。该池塘四周被茂密的植被环绕。
Description of the underwater landscape of the biotope: Because it’s a separate pond, the water hardly flows, and only when it’s windy can there be ripples on the surface. Leaves and branchs of nearby plants plants fall into the water, giving it a pale yellow color. The bottom is almost entirely composed of mud, in which some aquatic plant grow, small fish in groups shuttle between water and grass, occasionally slightly larger fish swim, snails and shrimps lie on the bottom of water and grass
生物群落的水下景观描述：由于这是一个独立的池塘，水流几乎静止，只有起风时水面才会泛起涟漪。附近植物的落叶和枝条掉入水中，使水体呈现淡黄色。底部几乎完全由淤泥构成，其中生长着一些水生植物；成群的小鱼在水草间穿梭，偶尔有稍大的鱼类游过，螺类和虾类则栖息在水底和水草上。
Description of the parameters of the habitat: the water is a little yellow, but transparent. Water temperature varies greatly from season to season, in summer some pond can approximately 30℃, but in winter, temperature below 20 degree. Water is close to neutral and has high hardness.
栖息地参数描述：水体略带黄色但透明。水温随季节变化显著，夏季某些池塘水温可达约 30℃，而冬季则低于 20℃。水质接近中性，硬度较高。

Threats to the ecology: As a developing country, China’s environment is not as good as that of developed countries. The pond environment in southern China is threatened by various factors. The first is pollution. Waste water from factories and chemical reagents used by some farmers have a great impact on the water quality of ponds. Next is the problem of species invasion. Many alien species, such as Trachemys scripta elegans,Oreochroms mossambcus, Gambusia affinis, Pomacea canaliculata and so on, do not have many natural enemies locally and are very competitive, which makes the local species in the same ecological niche great pressure. Some species carry diseases that are destructive to the local species. Moreover, local people have gradually increased the exploitation and utilization of the wild environment, and many fish habitats have been destroyed.
生态面临的威胁：作为一个发展中国家，中国的环境状况不如发达国家。中国南方的池塘环境受到多种因素的威胁。首先是污染问题。工厂排放的废水以及部分农民使用的化学试剂对池塘水质造成了严重影响。其次是物种入侵问题。许多外来物种，如红耳龟（Trachemys scripta elegans）、莫桑比克罗非鱼（Oreochromis mossambicus）、食蚊鱼（Gambusia affinis）、福寿螺（Pomacea canaliculata）等，在当地缺乏天敌且竞争力极强，给处于同一生态位的本地物种带来了巨大压力。部分外来物种还携带对本地物种具有破坏性的疾病。此外，当地居民对野生环境的开发利用逐渐增加，导致许多鱼类栖息地遭到破坏。
