One of the key tasks of ecopolis development is to enhance urban ecosystem service, especially the service of lung (urban green, forests and agriculture land), kidney, skin, exit, and artery (channels, roads and metabolism networks) so as to realize a state of purification, greening, vitalization and beautification. On the other hand, the goal of ecopolis is not only the "green" of natural ecosystem, but also the "red" of human ecosystem. The "eco" in ecopolis is neither a return to primitive nature or only environment protection, nor a conquer over nature, but a integration of green rhythm (blue sky, green field, fertile land, green water) and red network (industry, transportation, city and town, culture vein), a tradeoff between environment and economy and a harmony among heaven, earth and human.

生态城市建设的核心是要强化城市的肺、肾、皮、口和脉这些生态基础设施的服务功能，实现城市的净化、绿化、活化和美化；另一方面，生态城市不只要有自然生态的绿韵（蓝天、绿野、沃土、碧水），还要有人文生态的红脉（产业、交通、城镇、文脉）及其相互的融和，而不只是保护城市环境或生物。

Evapotranspiration is the largest and most difficult part to estimate in surface water circulation, and it also is an important process in interaction process between the land and atmosphere of land surface process. Its weightiness gets the recognition increasingly in the study of the global climate change. In many fields, the evapotranspiration have been applied.

蒸散是地表水循环中最大、最难估算的分量，同时也是陆面循环过程中地气相互作用的重要过程之一，在全球气候变化的认识和研究中，其重要性日益得到重视，并且在许多领域中得到了不同的应用。

Methods Marshland areas near high endemic villages of schistosomiasis in the Poyang Lake region were selected. Corresponding map was digitized and (Landsat 5 TM) the image was corrected according to the digital map. The image where water and land shifted during floody and dry seasons was extracted and classified by unsupervised method. The image in dry seasons was calculated by both Normalized Difference Vegetation Index and Tasseled Cap model. Traditional snail survey was done at the same areas and recorded the geographic position by Geographic Position System. Some cultured lands inside the embankment and water pound in marshland areas were selected as control group. Results The image of pilot areas was classified into 10 classes.

方法选择鄱阳湖区内3个洲岛型血吸病重度流行村周围的洲滩地图进行数字化，在数字化地图的基础上分别对两张Landsat 5TM卫星遥感片进行校正，并提取出冬陆夏水洲滩部分，运用ERDAS IMAGINE软件对此洲滩进行计算机非监督分类、校正植被指数(Normalized Difference Vegetation Index， NDVI)和穗帽湿度变换指数(Tasseled Cap， TC)模型计算；用传统方法进行螺情调查，卫星定位仪记录有钉螺点的经纬度，同时选择部分堤内的农田和水溏作为对照点。

The water body was extracted by combining density slicing of TM 5 or TM 7 with the terrain mask produced by DEM. NDVI was used to extract vegetation information, and desertification land and salification land information was extracted by the SAM classification method. Confusion matrix shows that the classification precision is 86.2%.
