摘要
生态功能区具有相似的生态服务功能或相似的生态系统敏感性.以福建莆田-惠安沿海城镇和集约化高优农业生态功能区内的耕地为研究对象,利用GIS技术对耕地的土地利用转移矩阵及不同坡度耕地变化进行分析.结果表明,2000—2010年间,研究区域内耕地面积减少121.14 km2,耕地转出以城镇为主,转入以林地为主.其中耕地的总变化量、交换变化量、净变化量及单类动态度分别为11.58%,8.98%,2.60%,30.18%.当耕地增加时,林地转换为耕地;当耕地减少时,耕地转换为城镇和草地,这2种情形都具有较强的倾向性.另外,莆田-惠安生态功能区的耕地减少且其分布具有向坡度较高的地方转移的趋势.
Ecological function zone has similar ecological study is focus on the characteristics of cultivated land in the sensitivity and ecosystem function service. The present eco-functional zone of Putian-Huian. The transformation matrix and stock map of cultivated land were accomplished by the GIS technology. The results showed that the overall area of cuhivated land decrease 121.14 km^2 from 2000 to 2010. The main decrease direction of cropland area has been changed from towns to forests. The amount of total change, swap change, net change and land use dynamic degree of cultivated land isl 1.58%, 8.98 %, 2.60%, 30.18%, respectively. When the cultivated land increased, forest land make into farm land. When the cultivated land decreased, it makes into towns and grassland. Both the situation has a strong propensity. The cropland in the eco-functional zone of Putian-Huian area has a decrease and switch to the location with higher gradient trend.
