    Analysis of Agricultural Non-point Source Pollution in A Small Watershed in Typical Mountainous Areas at Dongjiang Headwaters ——Taking the Dongjiang Watershed in Dingnan County as... by ZENG Jinfeng, PAN Hong, ZHANG Linan, ZHONG Jianhong, XIE Shuishi, ZHOU Shaomei

    Published 2023-01-01
    “…The current situation of agricultural non-point source pollution in a small watershed in typical mountainous areas at Dongjiang Headwaters were investigated and analyzed,and the agricultural non-point source pollution sources,pollution load and pollution load intensity in this watershed were analyzed,so as to provide a reference for ensuring the safety of water sources in the Guangdong-Hong Kong-Macao Greater Bay Area and promoting the precise pollution control in the watershed.The pollution types such as human settlements,agricultural planting,livestock and poultry breeding and aquaculture in the Dongjiang River Basin of Dingnan County were classified and investigated at the scale of county and township.The pollution load and pollution load intensity were estimated using the output coefficient method and the equivalent pollution load method,and the spatial distribution of pollutants was analyzed by clusteranalysis and ArcGIS.It was found that the main pollutants from agricultural non-point sources in the Dongjiang River Basin of Dingnan County were TN and NH<sup>+</sup><sub>4</sub>-N,which mainly came from human settlements and agricultural planting,and the pollution sources were concentrated in Lishi Town and Egong Town.Strengthening residents' awareness of water environmental protection,speeding up the construction of supporting sewage pipe networks,strengthening the operation and management of sewage equipments,and rationally applying nitrogen and phosphate fertilizers are of great significance for promoting the continuous emission reduction of agricultural non-point source pollution in the mountainous watershed at Dongjiang Headwaters.…”

    The effect of urban sprawl in emerging of transportation flows and urban air pollution in Tehran metropolitan region

    Published 2019-03-01
    “…For analysis of suburban spatial transportation have used Raw Data Intra-Urban and suburban Data in 1395 Year And for spatial analysis of air pollution (PM2.5 and PM10), have been used The raw data from sensing stations and Landsat satellite images (OLI) for three selected days in 1392, 1393, and 1395 as survey samples in the ArcGIS software. The research findings indicate that due to the intensity of transportation flows in Tehran metropolitan, the suburb to the suburb, the suburb to the central city (Tehran) and vice versa, Air pollution center Rise cannot be attributed to Tehran alone, as the area of pollutant sources has been distributed within the "Tehran metropolitan region ".So, the amount of spatial correlation between air pollution maps and transportation flow maps in selected days (2 Bahman 1392, 5 Bahman 1393 and Dec. 7, 1395), in all cases indicated high spatial relations (more than 75%), Confirmation the idea of this paper. …”
