【 摘 要 】

In this research the poem of Anne Finch, Countess of Winchelsea, “A Nocturnal Reverie” will be analyzed from an ecological perspective. Ann Finch’s contribution to understanding nature will be examined within ecocritical viewpoint and how her vision of nature is reflected in the poem. This study attempts to prove that Anne Finch was highly aware of the importance of nature in humans’ life and believed that humans are responsible for both nature and humans' welfare. With her poem Anne Finch tried to convince man that nature is a beautiful and living community that should be respected in order to reach inner harmony and to make the world a better, freer and kinder place. In the poem Finch represents nature as a united society, every part and aspect of which has its feelings, wishes and goals. Finch finds in natural society freedom and equality, but this is possible only at night. The day is the time of the “tyrant-man”, that belongs to a superior world and man suppresses the call of nature in himself. Still the tyranny of human cannot suppress nature completely because of the following reasons: a) man is not an authority, b) man feels the need in nature, and thus nature is superior to him. The study area is located north of the central part of Iraq. Some small cities lay within the area and Diyala River runs across it. It includes Himreen Lake in its middle part. The aims of this study was to develop and use applied approach for monitoring, detecting, analyzing and producing land use/cover change maps in Himreen and surrounding area during the period from 1984-2016, using remote sensing and geographic information system (GIS) techniques, as valuable contribution with high accuracy to planning and management in many fields of developments in the study area.Remote sensing techniques are used to produce Land Use/Cover (LULC) map for the study area using Landsat-8 satellite (ETM) images acquired in 2013. These images have the best compatibility properties for this purpose than other images attained in different dates, using USGS classification developed procedure. (LULC) map is produced depending on the maximum Likelihood supervised classification (ML) of (ETM) images with assessment accuracy of (97.44%) and (0.9707) kappa coefficient. In other hand, the change detection of water class in Himreen Lake has depended on the vector map of Normalized Difference Water Index (NDWI) of six scenes Landsat satellite series (ETM) images for the periods (1984, 1992, 2002, 2006, 2013, and 2016). The (LULC) raster and water index image are converted to vector structure, using ArcGIS v.10 software in order to create a digital (LULC) map.Three main classes of (LULC) are recognized in the mapped area. Those are Barren Land class (Code 7), the Barren Land Class is divided into four subclasses, which are Sandstone, Claystone, Mixed Exposed Land, and Bare soil. Agricultural Land class (Code 2), the Agricultural Land class is divided into two subclasses, which are Harvested Land and Idle Land. and Water class (Code 5), the Water class is represented by Himreen Lake. The mapped area revealed that the Barren Land Class covers the largest area, the Agricultural Land class and the Water class cover the smaller and smallest areas respectively. The Agricultural Land is represented in the eastern part of the mapped area in which the flood plain extends.Change detection of water in Himreen Lake is represented by increase and decrease periods. Three increase periods during years (1984-1992, 2002-2006, and 2013-2016) and two decrease periods during years (1992-2002, and 2006-2013) are detected. It is noticed that the decrease of water is referred to many reasons such as, shortage in rainfall, decrease in Diyala River flow release from upstream country, as well as the random irrigation acts in the study area.
