چکیده
Wetland is a unique ecosystem, rich in biodiversity. It is not only a valuable land resource, it also protects rare animals and plants, therefore it is of high economic value and scientific significance. This paper studies the present situation and development trends of wetland in Guangdong Province, China, with remote sensing technology. The total wetland area of Guangdong Province is 1 864 101 ha. The type, distribution, environment and use of wetland in Guangdong Province was investigated and wetland resource and environment were assessed in coastal areas. The strategies and countermeasures for wetland use and protection are recommended for decision making.

Discussion Reasons loss of Bamdzh wetland area with attention to the drought and the techniques of remote sensing
Bamdzh wetland of Khuzestan Province is at downstream of Shavvr River. Its area is approximately 4 hectares. Due to the loss of wetland area, especially in recent decades, this study investigated the effects of a five-year drought (2007-2012) in the Shavvr region and the pond ultimately. Also the comparison between the satellite images and remote sensing technique has been used and was estimat...
متن کاملInvestigation of changes of spatial autocorrelation patterns of chlorophyll-a in Choghakhor International wetland using hot spots index (Gi *) and remote sensing
Water resources such as wetlands, in addition to their economic and social importance, are ecologically valuable sources of aquaculture production. Due to its effects on aquatic environments, necessity of monitoring and awareness of the spatial and temporal distribution of chlorophyll-a is important for environmental studies. In the new approach to such studies, application of spatial statistic...
متن کاملComparative analysis of remote sensing water indexes for wetland water body monitoring using Landsat images and the Google Earth Engine Platform0 (A Case study: Meighan Wetland, Iran)
Wetlands are dynamic and complex aquatic ecosystems that play an important role in the survival of many plant and animal species. This study modeled the spatio-temporal changes of the Arak Meighan wetland during 1985–2020 using the multi-temporal Landsat images. In doing so, the applicability of different satellite-derived indexes including NDVI, NDWI, MNDWI, AWEIsh , AWEInsh , and WRI was inve...
متن کاملEffects of the land use change on ecosystem service value
The impacts of land utilization change on the ecosystem service values in Daqing during 1995 to 2015 were analyzed based on unit area ecosystem service value of Chinese territorial ecosystem from Mr. Xie Gaodi and ecosystem service value calculation formula from Costanza. Results showed that the ecosystem service value of Daqing decreased from US $4343.1559m in 1995 to US $3824.327m in 2015, wi...
متن کاملDetecting Surface Waters Using Data Fusion of Optical and Radar Remote Sensing Sensor
Identification and monitoring of surface water using remote sensing have become very important in recent decades due to its importance in human needs and political decisions. Therefore, surface water has been studied using remote sensing systems and Sentinel-1 and Sentinel-2 sensors in this study. In this paper, two data fusion approaches and decision fusion improve the accuracy of surface wate...
