一、塑(su)石(shi)假山能(neng)組織劃(hua)分、分隔空間
 利用塑(su)(su)石(shi)(shi)假(jia)山(shan)(shan)大(da)型(xing)建筑物特(te)性對園林空(kong)間(jian)(jian)(jian)進行分隔和(he)劃(hua)分，將空(kong)間(jian)(jian)(jian)分成大(da)小(xiao)不同、形(xing)狀各異、富于變化(hua)的(de)各種空(kong)間(jian)(jian)(jian)形(xing)態。通過(guo)塑(su)(su)石(shi)(shi)假(jia)山(shan)(shan)的(de)穿插、分隔、夾擁、圍合、聚匯，在塑(su)(su)石(shi)(shi)假(jia)山(shan)(shan)區可以創(chuang)造出山(shan)(shan)路的(de)流動(dong)空(kong)間(jian)(jian)(jian)、山(shan)(shan)坳(ao)的(de)閉合空(kong)間(jian)(jian)(jian)、山(shan)(shan)洞的(de)拱穹空(kong)間(jian)(jian)(jian)、峽谷(gu)的(de)縱(zong)深空(kong)間(jian)(jian)(jian)等各具特(te)色的(de)空(kong)間(jian)(jian)(jian)形(xing)式。塑(su)(su)石(shi)(shi)假(jia)山(shan)(shan)還能夠將游人的(de)視(shi)(shi)線或視(shi)(shi)點引到高(gao)處或低處，創(chuang)造仰視(shi)(shi)和(he)俯(fu)視(shi)(shi)空(kong)間(jian)(jian)(jian)景象。
 二、塑石假山是造景小品、點綴風景
 塑(su)石(shi)(shi)(shi)(shi)假山(shan)與(yu)石(shi)(shi)(shi)(shi)景(jing)(jing)(jing)景(jing)(jing)(jing)觀(guan)是自(zi)然(ran)山(shan)地(di)景(jing)(jing)(jing)觀(guan)在園(yuan)林中的藝術再(zai)現。在庭院中、園(yuan)路邊(bian)、廣場上、水池(chi)邊(bian)、墻角處，甚至在屋(wu)頂花園(yuan)等多(duo)種環境中，塑(su)石(shi)(shi)(shi)(shi)假山(shan)和石(shi)(shi)(shi)(shi)景(jing)(jing)(jing)還(huan)能(neng)作(zuo)為(wei)園(yuan)林小品，用來點綴風景(jing)(jing)(jing)、增添情(qing)趣，起到造(zao)景(jing)(jing)(jing)與(yu)點景(jing)(jing)(jing)的作(zuo)用。自(zi)然(ran)界的奇峰(feng)異石(shi)(shi)(shi)(shi)、懸崖峭壁、層巒疊嶂、深(shen)峽幽谷(gu)、泉石(shi)(shi)(shi)(shi)洞穴、海島石(shi)(shi)(shi)(shi)礁(jiao)等景(jing)(jing)(jing)觀(guan)形(xing)象(xiang)都可以通(tong)過塑(su)石(shi)(shi)(shi)(shi)假山(shan)石(shi)(shi)(shi)(shi)景(jing)(jing)(jing)在園(yuan)林中再(zai)現出來。
 三、塑石假(jia)山能因地(di)制宜、協調(diao)環境
 園林塑石(shi)假山能夠(gou)提(ti)供(gong)(gong)的(de)環(huan)境類型比(bi)平坦地形要多得多。在(zai)塑石(shi)假山區(qu)，不(bu)同坡度、不(bu)同坡向、不(bu)同光照條(tiao)件(jian)、不(bu)同土質、不(bu)同通風(feng)條(tiao)件(jian)的(de)情況隨處可尋，這(zhe)就給不(bu)同生(sheng)態習性的(de)多種(zhong)植物都提(ti)供(gong)(gong)了眾多的(de)良好的(de)生(sheng)長環(huan)境條(tiao)件(jian)，有(you)利于提(ti)高塑石(shi)假山區(qu)的(de)生(sheng)態質量(liang)和植物景觀質量(liang)。
