T he grow th in ten sity index (G II), w as emp loyed in stead of grow th speed to describe the spatial differen tiation of u rban land u se grow th. A ssisted by spatial analysis techn iques of G IS, the average G IIs per year (A G IIPY) of 155 comm unes o r tow n s du ring and w ere calcu lated and then classified th rough the N atu ral B reak s m ethod, and the spatial differen tiation m ap s of u rban land u se grow th in Beijing du ring and w ere m ade. T h is paper found: (1) Indu strial land is the mo st impo rtan t elem en t of u rban land u se grow th in Beijing, and its con tribu tion rate is on the increase, w h ich is differen t from the general W estern u rban grow th model driven by residen tial expan sion. Since 1982, the indu strial land had been keep ing expanded at the average rate of km 2 per year. It is ex trao rdinary h igh especially du ring the period, w h ile that of residen tial land and u rban land u se dropped by 59% and 24%, to 314 km 2 per year and 2918 km 2 per year respectively. T hu s, the con tribu tion rate of indu strial land to u rban land u se grow th increased from 64191% in to 80167% in (2) T he spatial pattern of u rban land u se grow th in Beijing w as in distinct concen tric sp raw l. W ith the grow th cen ters gradual sh ift from the inner to ou tside, the new 2added u rban land u se w ere increased in distinct concen tric zones and con tinually encroached upon the green spaces among the cen tral m ass and tho se dispersed con stellation s. T he to tal area of green spaces fo r iso lating bu ilt2up areas in General P lan of Beijing, w as 314 km 2 in 1958, reduced to 260 km 2 in 1983 and 160 km 2 in T he concen tric sp raw l pattern seriou sly destroyed the spatial structu re of dispersed con stellation s designed by the General P lan of Beijing, and also badly w o rsened the regional eco logical environm en ṫ (3) T he grow th axes of u rban land u se in the sou thern and eastern part of Beijing had stepped in to their decline period. T he sou thern and eastern part of Beijing is located in the N o rth Ch ina P la in and have advan tages in u rban developm en t sp ace, econom ic and tran spo rt comm un ication, etc., so that they are determ ined as the m ain u rban developm en t areas and direction by the latest General P lan ( ). But th is paper found, the tw o m ajo r grow th axes of u rban land u se along the Beijing2T ian J in and Beijing2Shen Zhen h ighw ays in the sou thern and eastern part of Beijing, had stepped in to their decline period du ring T heir A G IIPY decreased from 1163 and 1158 du ring to 0186 and 0167 respectively, and the spatial grow th pattern have also sw itched from vigo rou s ax ial expan sion to fill2in among axeṡ Key words: u rban land u se; spatial differen tiation; G IS; Beijing
