本篇文章主要讲述的是土地流失的原因和影响，土地流失最重要的原因是淹没。在许多沿海地区，土地流失的主要原因是淹没。这甚至可能指的是沿海地区可能由于海平面全面上升而造成的永久性洪水。据观察，全球海平面每年上升约1.8毫米。因为同样的原因，土地可能被淹没，所以土地会增加。大量的陆地被海水淹没(Tweel et al, 2014)。本篇利物浦论文代写文章由英国论文人EducationRen教育网整理，供大家参考阅读。
The most important cause of land loss is submergence. At many coastal areas, the primary reason for the land loss is submergence. This may even refer to permanent flooding in the coastal areas which may be caused because of the overall rise in the sea level. It has been observed that every year there has been a global rise of around 1.8 mm in the sea level. Because of the same, there is an increase in the land as it may be submerged. A large amount of land gets submerged into the water of the sea (Tweel et al, 2014).
The land loss is also influenced directly and indirectly by the rocky and sedimentary shores. It has been observed that in the areas northern pacific coast, the water is frozen quite often. Because of the freezing water there is the thawing of frozen water which may cause the wedging of ice leading to the expansion in the sea levels (Turnet et al, 1987). Because of the increase in thawing, there has been a significant loss of tundra in Alaska.
Land loss may also have a significant impact in the climate of the place. As a result of the draughts and wave attacks, the vegetation may be killed. Also, the lower water tables may also lead to the exposure of more dry sand, which may ultimately be removed nu wind. In addition to this, the grass fires may also be caused because of fragmentation (Penland et al, 2000).
In order to do the analysis of the Spatial Pattern and the analysis of the same for different categories of maps, FRASTATS is used. It is a computer software program which helps in the comparison of the landscapes of different varieties for a number of purposes. The software was released for the very first time in 1995 in the publication process of USDA Forest Service General Technical Report. In the year 2002, the program was combined and revamped with ArcGIS10. The most recent release of the software reflects the revamping of the same and it supports more and more cell level metrics, surface pattern metrics and other things. FRAGSTATS is useful as it provides the open source facility and flexibility, adjusts as per the results to the needs. In addition to this it is also useful that all the calculations are done in one script. Therefore it also saves the time.
