土地利用变化对太平池湿地区域生态系统服务价值的影响
Effects of Land Use Change on Ecosystem Services Value of Taipingchi Wetland Region
摘要
Abstract
Based on 1989,2000 and 2014 remote sensing image interpretation data,the characteristics of land use change of Taipingchi wetland region in Nong'an were extracted and analyzed.And the response in the relationship between change of land use and ecological environment evolution were also analyzed. Then the ecological services value of different land use types within the region was calculated.And in the study area the impact of land use change on ecosystem service function and their relationship were studied.The results showed that there were great changes of land use in Taipingchi wetland region in Nong'an during the period from 1989 to 2014,and the transformation trend of land use types belonged to the state of imbalance.The area of the cultivated land,residential land,bare saline-alkali patches and wetland had an increasing tendency,and the area of waters,grassland and woodland decreased duringthe period.The change of the cultivated land area and grassland area were more remarkable at 68.42 km2 increase and 92.2 km2 decrease respectively.The cultivated land,bare saline-alkali patches and wet-land was the main land type which affected by both natural factors and human factors,and the popula-tion was the main driving factors of land use change.Land use change led to the change of ecological en-vironment in the research area and influenced the ecosystem service value.The ecosystem service value mainly provided by the cultivated land and water,contribution rate more than 45% and 20% respective-ly.Most of the single service function value showed a trend of decrease.During the entire study,the loss of water source conservation function value is the most which is 21.7812 million yuan.Each land use type conversion is not conducive to the ecosystem service value in study area during the study period. Wetland is an important ecological system type,the ecosystem services value changes obviously affected by human activities,therefore,this study evaluated the land use changing by the influence of the wet-land ecosystem service value,the results of the study have great significance of regional ecological secur-ity evaluation.关键词
