Research On The Characteristics And Quality Of Local Stone Resources In Anshun City And The Application Strategy Of Architectural Landscape

With the vigorous development of Guizhou stone industry,in order to improve the competitiveness of Anshun local stone products,the local stone industry in Anshun City will be pushed to a broader market.This paper analyzes the mineral origin type,stone resource characteristics,development and utilization characteristics,appearance quality,engineering quality and durability of the local stone materials in Anshun City,and evaluates the landscape characteristics of the local stone building in Anshun from the aspects of index system construction,index weight analysis and comprehensive evaluation results,and concludes as follows:(1)Based on a large number of field investigation data and test data,it is concluded that the native stone resources deposit types in Anshun City can be divided into two types: sedimentary rock and metamorphic rock;according to sedimentary genesis,it can be divided into four types: sedimentary carbonate,sedimentary argillaceous terrigenous clastic rock,endogenous sedimentary rock and regional metamorphic rock;and it can be divided into six types according to the rock sub category: limestone,dolomite,shale,siliceous rock Rock,marble,slate.(2)A large number of data are obtained through various tests,and the quality characteristics of Anshun native stone products are obtained as follows: the mirror glossiness is: Horse yard stone(86),purple cloud marble(76),black wood grain(74),Athens wood grain(72),Beihuang stone(71);Shore hardness: horsestone 85(HSD),slate 61(HSD),limestone 60(HSD))The volume density of them are: slate 2.63(g/cm3),Athens grain 2.62(g/cm3),purple marble 2.61(g/cm3),black wood grain2.59(g/cm3),limestone 2.56(g/cm3),Beihuang stone 2.55(g/cm3),horsefield stone2.47(g/cm3);water saturated compression The shrinkage strength is 182(MPA),148(MPA)of Beihuang stone,145(MPA)of Machang stone,135(MPA)of slate,127(MPA)of limestone,98(MPA)for purple marble and Athens wood grain;the wear resistance is 28(1/cm3),26(1/cm3),27(1/cm3),22(1/cm3),18(1/cm3)for slate The water absorption of the stone is 1.70%,Athens wood grain 1.40%,black wood grain0.23%,slate 0.20%,purple marble(0.12%).(3)By consulting the relevant stone architectural landscape characteristics evaluation data and social investigation,Delphi method,AHP and fuzzy mathematics evaluation method are used to evaluate the landscape quality,engineering quality,durability and utilization value of the landscape evaluation system of Anshun local stone landscape;symbolism,aesthetics,practicability,strength,hardness,volume density,etc The weight evaluation of 12 secondary indexes,such as wear resistance,weathering resistance,economy,convenience,environmental protection and suitability,etc.The index weight of the index is from big to small: engineering quality(0.5511),utilization value(0.2642),durability(0.1171),landscape quality(0.0676);the second index weight is from big to small in order: strength(0.3609),economy(0.1378),hardness(0.1377),wear resistance(0.0976),suitability(0.0731),volume density(0.0525),practicability(0.0976),suitability(0.0731),volume density(0.0525),practicability(0.0976)The results show that the products are convenient(0.0346),weathering resistance(0.0195),environmental protection(0.0188),aesthetics(0.0132),and Symbolism(0.006).Combined with the weight analysis results of each sub item,the comprehensive evaluation of architectural landscape is carried out by introducing the quality inspection data of 7 kinds of stone products.The results are: black wood grain(8.655),green stone plate(8.277),horsefield stone(7.661),limestone(7.505),Beihuang stone(6.578),purple cloud marble(4.433),Athens wood grain(5.001).According to the research and analysis,the overall evaluation score of black wood grain stone is the highest,indicating that the products have obtained certain competitive advantages and deserve further promotion;while the research and development of the stone products of Beihuang stone,purple cloud marble and Athens wood grain stone products still need to increase the research and development of the stone products to fine and deep stone products,so as to improve the combination competitiveness and the combination competitiveness of local stone products in Anshun City Group brand effect.According to the above analysis and research,combined with the local culture and regional cultural value of Anshun local stone in various local architectural landscapes,and the unique national cultural connotation contained in it,the corresponding research strategies of the application of local stone landscape in Anshun City are proposed.
