【摘要】：丹霞地貌系指由水平或緩傾斜的層狀紅色碎屑巖(主要為礫巖、砂巖、粉砂巖)組成的具有陡崖坡的紅層地貌,其特殊的形態(tài)特征及地層組成賦予了該種地貌較強(qiáng)的造景能力,在構(gòu)造切割、重力崩塌、流水侵蝕、風(fēng)化作用等綜合作用下,易形成千姿百態(tài)、形態(tài)逼真的造型景觀。這些丹霞造型景觀是珍貴的旅游資源,具有獨(dú)特性和不可再生性。隨著“中國(guó)丹霞”申遺的成功,對(duì)造型景觀基礎(chǔ)地質(zhì)理論的深入研究已成為當(dāng)前的急切需求。信江盆地處于揚(yáng)子古板塊和華夏古板塊的接合部,是我國(guó)丹霞地貌發(fā)育最為突出的地區(qū)之一。受大地構(gòu)造位置和內(nèi)外地質(zhì)作用的影響,盆地內(nèi)形成了大量的丹霞地貌,如石峰、石崖、石柱、峰林、峰叢、石梁、穿洞、巖洞等。隨著丹霞地貌的不斷發(fā)育演化,形成了許多極具科研及旅游觀賞價(jià)值的丹霞造型景觀,代表性景觀有:龍虎山的金槍峰、仙女巖、象鼻山,龜峰石龜、老人峰、八戒峰、天外來(lái)客、三疊龜,六石巖石象,廣豐羚羊石等。根據(jù)丹霞造型景觀的形態(tài)類型,本文將信江盆地丹霞造型景觀分為石峰造型景觀、孤峰殘石造型景觀、穿洞造型景觀、石龜造型景觀及組合型造型景觀。通過(guò)對(duì)這五類造型景觀發(fā)育特征的研究發(fā)現(xiàn),殘峰孤石、峰林、峰叢、石叢、穿洞、陡峻石峰等丹霞地貌較易形成造型景觀,丹霞丘陵、石墻、小石峰等丹霞地貌不易形成造型景觀。孤峰殘石型、穿洞型及石龜造型景觀通常為溶蝕風(fēng)化成因,由巖性差異較大的巖層組成,以鈣質(zhì)膠結(jié)、泥質(zhì)膠結(jié)為主;石峰型、組合型造型景觀通常為崩塌成因或流水成因,巖石組成較均勻,以鐵質(zhì)膠結(jié)為主。此外,信江盆地造型景觀主要分布于盆地邊緣地區(qū),以盆地南緣最為發(fā)育,位于盆地中部和邊緣之間的過(guò)渡地帶偶有發(fā)育,盆地中部基本不發(fā)育。丹霞造型景觀演化程度一般較高,以壯年晚期-老年早期為主,盆地北緣及盆地過(guò)渡地帶偶見(jiàn)壯年早期的造型景觀。綜上可知,丹霞造型景觀的形成具有一定的偶然性,不是所有丹霞地貌都能發(fā)育成造型景觀。紅層條件、構(gòu)造條件及外動(dòng)力條件是丹霞造型景觀形成的必要前提,是主要的成景條件。
[Abstract]:Danxia landform refers to layered red clastic rocks by horizontal or gently inclined (mainly for conglomerate, sandstone, siltstone) which has the steep slopes of red beds landforms, its special morphological characteristics and the stratigraphic composition gives the landform landscaping strong ability in the construction of cutting, gravity collapse, water erosion, comprehensive effect of weathering, easy to form a lifelike shape in different poses and with different expressions, the Danxia landscape is a landscape. Other precious tourism resources, unique and non renewable. With the "Chinese Danxia successful inscription, in-depth study of the basic theory of geological landscape modeling has become the urgent needs of the current in the Xinjiang basin. Junction of Yangtze paleo plate and Cathaysian plate, Danxia landform of China's development is one of the most prominent areas. Affected by tectonic and geological action, the formation of a large number of Danxia Basin Such as landform, peaks, cliffs, pillars, peaks, peaks piercing, cave Shilianghe, etc. with the development of Danxia landform evolution, the formation of the Danxia landscape tourism research and many other highly ornamental value, representative landscape: Mount Longhu tuna peak, a fairy rock, the turtle, the old elephant trunk hill. Eight peak, peak, extraterrestrial, stacked three turtles, six stone, stone Guangfeng antelope etc. according to the types of shape of Danxia landscape, the Xinjiang basin, Danxia style landscape is divided into other Shifeng landscape, Gufeng residual stone other landscape, piercing other landscape, landscape and other combination of other turtle through the research landscape. Other features of the five kinds of landscape development, the residual peak peaks, peak cluster, boulders, stones, piercing, steep Shifeng Danxia landform is easy to form other landscape, Danxia hills, stone walls, small stone Danxia landform is not easy to form a Butte landscape. The residual stone, and other landscape type piercing turtle usually causes corrosion and weathering, composed of different strata lithology, with calcium cementation, clay cementation; combination of other landscape type peaks, usually collapse cause or causes water, rock composition is uniform, with ferruginous cementation. In addition, the Xinjiang basin modeling the landscape is mainly distributed in the edge of the basin to the south margin of the basin area, the most developed, located between the center and the edge of the basin transition zone with development, no development in the central part of the basin. Danxia style landscape evolution is generally higher, with strong in late - early old age, northern margin of the basin and occasionally in the early transition zone of other landscape. To sum up, has a certain chance to form shape of Danxia landscape, not all Danxia landform can develop into other landscape. The red layer conditions, structural conditions and dynamic conditions in Danxia The necessary precondition for the formation of the styling landscape is the main setting condition.
