Global warming has obtained more and more attention because the global mean surface temperature has increased since the late 19th century. As more than 50% of the human population lives in cities, urbanization has become an important contributor for global warming. Pearl River Delta (PRD) in Guangdong Province, southern China, is one of the regions experiencing rapid urbanization that has resulted in remarkable Urban Heat Island (UHI) effect, which will be sure to influence the regional climate, environment, and socio-economic development. In this study, Landsat TM and ETM+ images from 1990 to 2000 in the PRD were selected to retrieve the brightness temperatures and land use/cover types. A new index, Normalized Difference Bareness Index (NDBaI), was proposed to extract bare land from the satellite images. Additionally, Shenzhen, which has experienced the fastest urbanization in Guangdong Province, was taken as an example to analyze the temperature distribution and changes within a large city as its size expanded in the past decade. Results show that the UHI effect has become more prominent in areas of rapid urbanization in the PRD region. The spatial distribution of heat islands has been changed from a mixed pattern, where bare land, semi-bare land and land under development were warmer than other surface types, to extensive UHI. Our analysis showed that higher temperature in the UHI was located with a scattered pattern, which was related to certain land-cover types. In order to analyze the relationship between UHI and land-cover changes, this study attempted to employ a quantitative approach in exploring the relationship between temperature and several indices, including the Normalized Difference Vegetation Index (NDVI), Normalized Difference Water Index (NDWI), Normalized Difference Bareness Index (NDBaI) and Normalized Difference Build-up Index (NDBI). It was found that correlations between NDVI, NDWI, NDBaI and temperature are negative when NDVI is limited in range, but positive correlation is shown between NDBI and temperature.

选择了珠江口及其邻近海域1995年~2000年152个时相的NOAA/AVHRR影像反演的悬浮泥沙浓度结果,通过对悬浮泥沙反演结果影像的叠加,求算叠加像素点像素平均值,计算了研究海域在1995~2000年间月、季及丰枯水期几个时间尺度上的悬浮泥沙平均浓度及其平均变化。结果大致表明了陆地径流对海域的影响范围和悬浮泥沙在海域的运动方向。

The spatial patterns of water quality were studied by integrating a Landsat TM image, 58 in situ water quality datasets and 30 samples from two concentration maps of water quality parameters derived from SeaWiFS and NOAA/AVHRR images in the Pearl River estuary and the adjacent coastal waters of Hong Kong. The reflectance of TM bands 1–4 was derived by using the COST method. The normalized difference water index (NDWI) was extracted from the raw image and the threshold segmentation was used to retrieve the water pixels of spectral reflectance. In order to study the spectral reflectance categories related to water quality, a dataset comprising 88 sampling points from four spectral bands of a Landsat TM image was used. The samples were positioned according to the availability of water quality parameters in the study area, and five reflectance classes could be finally distinguished by using the cluster analysis. Three supervised classifiers, maximum likelihood (MLH), neural network (NN) and support vector machine (SVM), were employed to recognize the spatial patterns of ocean color. All the 88 samples were divided into two data sets: 65 in the training data set and 23 in the testing data set. The classification results using the three methods showed similar spatial patterns of spectral reflectance, although the classification accuracies were different. In order to verify our assumption that the spatial patterns of water quality in the coastal waters could be indirectly detected by ocean color classification using the Landsat TM image, five optically active water quality parameters: turbidity (TURB), suspended sediments (SS), total volatile solid (TVS), chlorophyll-a (Chl-a) and phaeo-pigment (PHAE), were selected to implement the analysis of variance (ANOVA). The analysis showed that a statistically significant difference in water quality clearly existed among the five classes of spectral reflectance. It was concluded that the five classes classified by reflectance showed distinct water quality characteristics. Therefore, the ocean color classification based on landsat TM images and regular measurements of water quality may provide a reasonable spatial distribution for the coastal water quality. This may serve as an effective tool for the rapid detection of changes in coastal water quality and subsequent management.

选取香港海域7个水环境控制区在1988~1999年期间每月或每半月定位连续取样的37个水质测站,每个测站选用17个水质参数,研究香港海域海岸带水体叶绿素-a浓度及其相关因子的时空分布规律。对37个测站17个参数作聚类分析,结果表明,香港海域东部由半封闭海湾组成的水域控制区,其赤潮发生频率较高;西部水域属于河口环境。多变量分析结果表明,BODS,对叶绿素-a浓度普遍存在显著性影响,氮和光照条件在东部海域对叶绿素-a浓度的影响比西部海域更显著,而磷以及包括盐度、温度、溶解氧和pH在内的海洋物理化学条件在西部海域有更显著的影响。在整个香港海域,年内平均最高叶绿素-a浓度主要出现在冬末春初和夏末秋初,东部海域的年平均叶绿素-a浓度一般高于西部海域。香港海域的叶绿素-a浓度普遍存在一个8~10年的周期性变化规律。

【期刊论文】FLOOD SIMULATION IN THE COASTAL LOWLANDS OF NORTHERN JIANGSU, CHINA
陈晓玲, CHEN Xiaoling
Geo-spatial Information Science Vol.2, No.1, p. 35-41 Dec. 1999,-0001,():
-1年11月30日
The coastal lowlands in northern Jiangsu Province, China, is characterized by low relief and low water surface gradient in streams. The flooding stages are commonly lower than the high-tide level and the tidal range is relatively small. All these factors prohibit rapid discharge of floodwater and make the flood regimes here extremely sensitive to the sea level rise. The 1991 Plum Rain was examined, when precipitation was significantly higher than normal. The one-dimensional open-channel non-conservative flow model was used to simulate the stream flow in the channel network of studied area. GIS technology was used to delineate the maximum in undated area by analyzing the DEMs.
