【摘要】 利用1996—2004年湛江市土地利用变更数据,在研究土地利用变化的基础上,从时空角度分析生态系统服务价值(ESV)变化。研究结果表明:①1996—2004年,湛江市耕地、林地、牧草地面积在减少,其中耕地减少最多,减少了11954.1hm2;园地、居民点及工矿用地、交通用地、未利用土地面积在增加,其中居民点及工矿用地增加最多,增加了7696.4hm2。②1996—2004年,湛江市总ESV在缓慢减少,减少了0.57亿元,变化率-0.44%;湛江市生态系统单项服务功能价值(ESVf)变化的总体趋势是:气体调节、气候调节、土壤形成与保护、生物多样性保护、食物生产、原材料在减少,水源涵养、废物处理、娱乐文化在增加;不管是整体生态系统服务功能,还是单项服务功能,湛江市各县区都在减弱。更多还原

【Abstract】 This paper analyzed the spatial-temporal changes of ecosystem services value(ESV) based on the data of land use from 1996 to 2004 in Zhanjiang City.The results showed:(1) the areas of cultivated land,forest land and grass land decreased,while those of garden land,residential area,industrial and mineral land,traffic land and unutilized land increased;the area of cultivated land decreased most by 11954.1 hm2,and the area of residential area,industrial and mineral land increased most by 7696.4 hm2.(2) the total ESV decreased by $0.5716 billion,and the rate of change was-0.44%;the value of single ecosystem services function(ESVf) of gas regulation,climate regulation,soil formation,bio-diversity conservation,food production and raw materials decreased,while those of water conservation,waste treatment and recreation increased;not only the whole function but also each function of ecosystem services weakened in all the districts of Zhanjiang City.更多还原
