红树林为分布于热带和亚热带海岸潮间带的木本植物群落，是淤泥质海滩上特有的植被类型，也是重要的海岸湿地资源，作为独特的海陆边缘生态系统在维持海岸生态平衡中起着特殊的作用。 建立科学、适用的红树林类型划分模型是最为基础性的工作。及时准确地掌握红树林群落现状信息可为保护和修复红树林生态系统提供重要决策依据。对红树林群落进行遥感分类在实际应用中具有较大的意义。 由于红树林的生长地域特点，常规的野外调查比较困难，工作量大费用高。遥感技术具有观测范围广、信息量大、获取信息快、更新周期短、可比性强等优点，已被广泛用于红树林调查检测中。但目前采用的TM图像存在空间分辨率不高，以及红树林群落间较强的光谱相似度等问题，,有必要采用更为智能化的方法来提高分类的精度。 |

第二段Establishing a scientific and applicable mangrove classification model is the most basic work. Grasping the status of mangrove communities timely and accurately can provide important information on the decision-making basis for the protection and restoration of mangrove ecosystems.Mangrove communities in remote sensing classification has great significance in practical applications. |

第三段 Because of the geographical features of the growth of mangroves,Conventional field investigation is difficult and heavy workload ,it also costs too much.Remote sensing technology has a wide range of observations and the amount of information is big, besides accessing to information faster compared to other advantages.It has been widely used in the detection of mangrove survey.But the presence of TM images using spatial resolution is not high and we have the problem of mangrove communities strong spectral similarity.Due to these problems , we need to adopt a more intelligent approach to improve the accuracy of classification.译的不好还望见谅，呵呵呵 |
