China's 18,340 km coastline. Coastal climate variability, natural disasters, coastal protection forest is a green screen on coastal zone, which can effectively improve the coastal environment. Since reform and opening, China's rapid economic development in coastal areas, but destroy the ecological environment, especially the coastal protection forest.Jinjiang is located in the southeast coast of Fujian Province ranked first in total economic output. Shelterbelt planting in 1956, is typical of our province shelter construction. Currently, its economic development is in outstanding contradictions with coastal protection forest, so this article take Jinjiang as a study area. according to landscape ecology, remote sensing image as data source to explore the coastal protection forest area change, on analysis of changes in coastal protection forest we can provide a scientific basis for the restoration of coastal shelterbelts.As follow:(1)using methods of landscape ecology, coastal protection forest in Jinjiang dynamic changes of landscape pattern analysis, we learn that the coastal protection forest area of 20 years, Jinjiang, the overall change wavy. Specifically in 1989-2001 decreased greatly, in 2001-2004 rebounded,2004-2008 also showing a downward trend.(2)through the analysis of shelter's benefit, economic restructuring is known the reason for the shelter change.1993 shift from primary industry to secondary industry, in 2004 from the secondary industry to tertiary industry, the shelter was undermined, the shelter area is reduced; in 2001 when the development went into the middle and late industrialization, people began to attach importance to the ecological environment, the overall shelter was recoveried.(3)the use of AHP, on the shelter's benefit analysis, we can see, after the coastal protection forest destruction, whether in the strong wind zone, transition zone, or weak wind area, benefits have decreased in varying degrees, in the strong wind area decreased significantly, while the weak wind area less affected, it must hold strong wind protection forest.(4)under-benefit analysis, efficiency decreased significantly after the destruction of shelter, rehabilitation and reconstruction so as soon as possible, but also discriminate between different coastal zones. The Principle of Near natural garden, with strong winds in the coastal zone of reasonable importance of vegetation configuration, simulation of natural vegetation patch structure, and promote the natural succession of communities, while the weak wind zone protection forest belt in the building to beautify and promote the development of coastal tourism and other industries(5)known in this study, the economic development of the coastal zone is an extension of the trend, the shelter should be combined with economic development along the coast. Jinjiang at the forefront of economic development in coastal areas, and other coastal cities and counties for future economic development and protection forest protection will be even more widespread conflict, we should take the protective forest as an important part of future research.
