Gains and losses in ecosystem service values (ESV) in coastal zones in Zhejiang Province during rapid urbanization were analyzed in terms of land-use changes. Decision-making on coastal development based on ESV estimation is significant for the sustainable utilization of coastal resource. In this study, coastal land-use changes in Zhejiang Province during rapid urbanization were discussed based on remote-sensing derived land-use maps created in the years 1990, 2000 and 2010. The ESV changes in coastal zones in Zhejiang Province from 1990 to 2010 were estimated by using the established ESV estimation model. The analysis results demonstrate the following: (1) with the …
Analysis Of Water Quality For Lake Tarpon, Pinellas County, Florida, Kristi Nichole Savio
Analysis Of Water Quality For Lake Tarpon, Pinellas County, Florida, Kristi Nichole Savio
USF Tampa Graduate Theses and Dissertations
Urbanization has taken a major toll on the water quality of Lake Tarpon. In response, there have been management strategies and legislation put in place to help improve water quality. Our objective was to identify what management strategies and other environmental factors were driving changes in Lake Tarpons water quality from 1970 - 2010. Trends in water quality were analyzed against precipitation, land use and water quality management strategies to achieve this. Results found that two water quality management strategies, the creation of the Lake Tarpon Outfall Canal and the closing of the Lake Tarpon Sink, improved water quality the …
Land Use In The Karstic Lands In The Mediterranean Region, Ibrahim Atalay
Land Use In The Karstic Lands In The Mediterranean Region, Ibrahim Atalay
International Journal of Speleology
Karstic lands have special importance in terms of soil formation and land-use. Soil appears only on the flat and slightly undulating karstic lands, while soils are found along the cracks and bedding surfaces between the layers on the hilly karst areas although these lands are rocky in appearance. Karstic lands in the hilly area are not conducive to cultivation. But rocky areas create a favourable habitat for the growth of forests except in an arid climate. Because the tree roots easily follow and develop along the cracks in the limestone. As a general rule soil erosion does not occur on …

Moravian karst is a narrow strip of limestone with long history of settlement, agricultural use and man impact to karst. It is naturally divided into smaller units - karst plateaus - separated by deep valleys (glens). Each plateau has different proportion of land use, i.e. the percentage of agricultural land, forests, etc. The agricultural land constitutes now up to 70% in the north and max. 30% in the centre and south of the total area of plateaus. Intensive agricultural use of the arable land since 60ties of this Century caused great impact to quality of soils and groundwater by overdoses …

The karstic regions of the municipalities of Peruaçu, Januária and Jaiba present a variety of soil uses which are a function of the organization of the karstic relief. This relief system forms a rift, which received fluvial sediments deposition from the São Francisco River. The horst of the Peruaçu plateau is developed on limestone rocks of Late Proterozoic age with a high concentration of calcium carbonate. The South American Surface was formed on this and is today occupied by cattle ranching. In the graben, due to easy irrigation from underground karst waters and because of the nearby drainage system of …
