前人都是採用樣方方法對格氏栲種群數量的空間格局進行測定,而格局分佈有可能受樣方大小的影響,且分析過程中沒有涉及聚塊間密度差的問題,因而無法掌握種群的聚塊大小差別及聚塊內個體間的離散程度.本研究採用無樣方距離法,測定不同生境的格氏栲種群空間格局,分析格氏栲種群格局的強度和紋理.強度以聚塊和間隙的密度差來定義,紋理則是體現聚塊內個體間的離散程度與諸聚塊間的分離程度.測定結果表明,格氏栲種群格局強度從高到低排列次序為:木姜子蚊母樹冬青茜草樹格氏栲米櫧虎皮楠木荷;格局紋理從粗到細的順序是:木荷=木姜子茜草樹格氏栲=冬青米櫧蚊母樹虎皮楠.這一測定結果與作者採用聚集度指標測定相同樣地格氏栲種群空間格局的結果基本相符.因此,格氏栲空間格局類型及分佈與格氏栲生物學特性及生境的關系密切First, based on location theories and systems model methods, the location factors were quantified by establishing the location advantage models ( including economic attraction model and spatial aggregation model ) and location feasibility models. the location advantage grades and location feasibility types were set up, according to the result of location models of daxing district. secondly, based on the landscape analysis of the 4 towns chosen form location grades system, the landscape status has been judged by landscape pattern analysis, then the relationship of location typies and landscape pattern has been analyzed

( 2 ) the performance of pc was decided with the proportion of pea, aa, mma. the fluidity of copolymer would augment if the dosage of aa increase, but when dosage of aa was 75 %, it was hard to control the compose reaction, and dispersion of pc would depress ; when pea degree of polymerization augment the air - entraining of mma would increase ; it would produce floe and hard to control the compose reaction when the dosage of pea4 more than 15 %, pea23 more than 25 %
( 2 ) pea 、 aa 、 mma之間的比例關系決定了共聚體的性能:隨著丙烯酸用量的增加,共聚體的流動度增大,達到75時合成控制難度加大,共聚體分散性下降;而mma的引氣增穩作用,其用量隨著pea的聚合度的增加而增加, pea4體系的用量超過15 , pea23體系超過25則會產生絮狀物,反應控制難度加大,理想的用量分別為不超過10和15 。Tangpu children ' s wear has already got high well - knownness in china, and tangpu has been a center where children ' s wear enterprises gathers
