简述了生态足迹方法,对生物资源消费帐户和化石能源消费帐户的涵盖范围进行了界定.根据1990~2005年广东省广州市花都区土地利用及生态环境的相关数据,利用生态足迹分析方法研究了广州市花都区土地消费性功能的需求、供给及供需差异变化情况.结果表明,1990~2005年,人均生态足迹与生态足迹总量均呈迅速增长的趋势,生物资源消费所占比例较化石能源存在绝对优势,化石能源足迹增长速度快于生物资源足迹,但生态足迹总量的结构并未发生明显变化;花都区土地消费性功能的需求远远超出了该区的生态承载力,但其土地利用强度并未超出支撑土地利用系统消费性功能持续产出的生态环境阈值,从而说明花都区生态环境系统仍然是比较安全的.
簡述瞭生態足跡方法,對生物資源消費帳戶和化石能源消費帳戶的涵蓋範圍進行瞭界定.根據1990~2005年廣東省廣州市花都區土地利用及生態環境的相關數據,利用生態足跡分析方法研究瞭廣州市花都區土地消費性功能的需求、供給及供需差異變化情況.結果錶明,1990~2005年,人均生態足跡與生態足跡總量均呈迅速增長的趨勢,生物資源消費所佔比例較化石能源存在絕對優勢,化石能源足跡增長速度快于生物資源足跡,但生態足跡總量的結構併未髮生明顯變化;花都區土地消費性功能的需求遠遠超齣瞭該區的生態承載力,但其土地利用彊度併未超齣支撐土地利用繫統消費性功能持續產齣的生態環境閾值,從而說明花都區生態環境繫統仍然是比較安全的.

Ecological Footprint Method is introduced to define the range of biological resource consumption account and fossil energy consumption account. According to the relevant data of land use and ecological environment in Huadu District, Guandzhou City, Guangdong Province, China from the year 1990 to 2005, ecological footprint analysis method is used to research on the demand and supply of land consumption function of Huadu District, as well as the difference variation between supply and demand. Result shows that per capita ecological footprint and total ecological footprint have increased sharply from 1990 to 2005. Biological resource consumption has an absolute advantage of proportion compared with fossil energy. Growth speed of fossil energy footprint is faster than that of biological resource footprint. However, structure of total ecological footprint has not changed significantly. Demand of land consumption function is far beyond the ecological carrying capacity of Huadu District. But land use intensity has not exceeded the ecological threshold produced by supporting consumption function of land use system, indicating that ecological environment system is still relatively safe in Huadu District.
