This study aims at the classification and water quality assessment of Harike wetland (Ramsar site) in India using satellite images from the Indian Remote Sensing satellite, Resourcesat (IRS P6). The Harike wetland is a converging zone of two rivers, Beas and Sutlej. The satellite images of IRS Linear Imaging Self Scanner (LISS) IV multispectral sensor with three bands (green, red, and near infrared (NIR)) and a spatial resolution of 5.8 m were classified using supervised image classification techniques. Field points for image classification and water sampling were recorded using a Garmin eTrex Global Positioning System. The water quality parameters assessed were dissolved oxygen, conductivity, pH, turbidity, total and suspended solids (SS), chemical oxygen demand, and Secchi disk transparency (SDT). Correlations were established between turbidity and SS, SS and SDT, and total solids and turbidity. Using reflectance values from the green, red, and NIR bands, we then plotted the water quality parameters with the mean digital number values from the satellite imagery. The NIR band correlated significantly with the water quality parameters, whereas, using SDT values, it was observed that the green and the red reflectance bands were able to distinguish the waters from the two rivers, which have different water qualities. 相似文献

Agenda 21, the Habitat Agenda and the United Nations Convention on the Rights of the Child have brought new relevance to Growing Up in Cities, a project of participatory action-research for urban children and youth. The origins of the project in the 1970s under the leadership of the urban planner Kevin Lynch are described, along with a brief history of the project's revival. The results of the project's recent implementation in eight countries are summarised with an emphasis on children's perspectives on environmental quality, as well as lessons learned regarding how children can be most effectively integrated into LA21 processes. 相似文献

The development activities in mountainous region though provide comfort to the human being and enhance the socioeconomic status of the people but create pressure on the bio-resources. In this paper, the current status of land use/landcover and the vegetation communities of the Solang valley watershed in Himachal Pradesh of Indian western Himalaya has been mapped and presented using remote sensing. This watershed area was dominated by alpine and sub-alpine pastures (30.34%) followed by scree slopes (22.34%) and forests (21.06%). Many tree, shrub, and herb species identified in the study area are among the prioritized species for conservation in the Indian Himalayan Region. Thus, scientific interventions and preparation of action plans based on ecological survey are required for conservation of the Solang valley watershed. 相似文献

The contribution of spraying DDT and HCH for malaria control towards the contamination of bovine milk was investigated by analysing milk samples collected from preselected localities sprayed with either DDT or HCH in the Punjab. A direct correlation was found between the amounts of residues of these insecticides in milk and their typical usage pattern for the mosquito control programme. It is considered that these results may have significant bearing on the regulatory control of DDT and HCH residues in milk. 相似文献
