Two methods , the stereo - analytical method and the time - vector method used for calcu1ation are ones through parallel moving discontinuous surfaces 所采取的赤平投影方法和矢量分析法均是平移結(jié)構(gòu)面進(jìn)行計(jì)算。
In addition , the thesis has gained a little innovative achievements which are differ from other scholars , such as classifying the carrying objects of environmental carrying capacity , establishing the index system of environmental carrying capacity , unifying dimentions , modifying the initial coefficients and making use of hierarchy and vector analytical method to analyze environmental carrying capacity quantificationally 本文在環(huán)境承載力承載對象的分類、環(huán)境承載力指標(biāo)體系的構(gòu)建、統(tǒng)一量綱的方法、初始權(quán)重的修正以及采用層次矢量分析法量化研究環(huán)境承載力等方面進(jìn)行了不同于其他學(xué)者的新嘗試。
Thirdly , designs the index system of nanjing ’ s environmental carrying capacity and uses hierarchy and vector analytical method to research nanjing ’ s environmental carrying capacity among the years of 1997 and 2003 . subsequently , the author analyzes the environmental carrying quantity , environmental carrying capacity , environmental carrying rate and their variational trends from 1997 to 2003 in detail . lastly , according to the above results , puts forward some measures to protect and advance nanjing ’ s evironmental carrying capacity 本文圍繞著南京市環(huán)境承載力這一研究主線,首先從定性、定量兩種角度對環(huán)境承載力的國內(nèi)外研究現(xiàn)狀進(jìn)行綜述;接著介紹了環(huán)境承載力理論的基本內(nèi)容和南京市自然環(huán)境、社會經(jīng)濟(jì)狀況;然后切入論文的核心部分,構(gòu)建了多層次的南京市環(huán)境承載力指標(biāo)體系,運(yùn)用層次矢量分析法對1997 ~ 2003年南京市環(huán)境承載力及其變化情況加以量化研究,并以此計(jì)算結(jié)果為依據(jù),詳細(xì)分析了1997 ~ 2003年間南京市環(huán)境承載量、環(huán)境承載力、環(huán)境承載率的變化趨勢;最后,針對上述分析結(jié)果提出保護(hù)和提升南京市環(huán)境承載力的幾點(diǎn)策略。
