【摘要】：目前我國對城市建設用地適宜性評價多采用定性的分析方法，帶有較大的主觀性。本文利用GIS強大的空間數(shù)據(jù)分析能力，充分吸收層次分析法和粗糙集理論兩類評價方法的優(yōu)點，通過建立工程地質條件適宜性影響因素綜合評價指標體系，將層次分析法確定的主觀權重與粗糙集理論確定的客觀權重進行有機集成得到組合權重，使得工程地質條件適宜性影響因素的評價更具客觀性，提高了評價精度；并結合模糊綜合評判法來判定城市建設用地的適宜性。 本文根據(jù)深度以及地基形式的不同將研究區(qū)建設用地分成天然地基持力層（小于5m）、復合地基持力層（5-8m、8-15m）及樁基持力層（15-20m、20-25m、25-30m、30-65m），，分別進行評價，進而將研究區(qū)劃分成適宜區(qū)、較適宜區(qū)、適宜性較差區(qū)和適宜性差區(qū)。經(jīng)過評價得出，除了滹沱河范圍內以及周邊20m為限建區(qū)，天然地基適宜性分區(qū)由好到差所占面積百分比依次為70%、15%、15%、0%；5-8m復合地基適宜性分區(qū)依次為50%、30%、20%、0%；8-15m復合地基適宜性分區(qū)依次為70%、20%、10%、0%；15-20m樁基適宜性分區(qū)依次為90%、5%、5%、0%；20-25m樁基適宜性分區(qū)依次為95%、5%、0%、0%；25-30m、30-65m樁基適宜性分區(qū)為都適宜；所得出的評價結果為將來石家莊市的城市規(guī)劃提供有力的科學依據(jù)。
[Abstract]:At present our country to the city construction land suitability evaluation using the method of qualitative analysis, with great subjectivity. GIS's powerful ability of spatial analysis in this paper, fully absorb the merits of AHP and the theory of two kinds of evaluation methods of rough set, through the establishment of the engineering geological conditions suitable for the comprehensive evaluation index system of influence factors. The analytical hierarchy process method to determine the subjective weight and the objective weight theory of rough set are integrated by organic combination weights, the engineering geological conditions suitable for evaluating influence factors more objective, improve the accuracy of evaluation; combined with fuzzy comprehensive evaluation method to determine the suitability of the city construction.
The depth and the foundation of different forms of the construction land will be divided into the natural foundation bearing layer according to the (less than 5m), the composite foundation bearing layer (5-8m, 8-15m) and bearing layer (15-20m, 20-25m, 25-30m, 30-65m), were evaluated, and will study the division into suitable area, suitable area, suitability of poor areas and suitable poor area. After the evaluation, in addition to the Hutuo River within and around the 20m within the construction area, the natural foundation suitability zoning from good to bad area percentage were 70%, 15%, 15%, 0%; 5-8m composite foundation suitability were 50%, 30%, 20% 0%, 8-15m; composite foundation suitability zoning were 70%, 20%, 10%, 0%; 15-20m pile foundation suitability zoning were 90%, 5%, 5%, 0%; 20-25m pile foundation suitability zoning were 95%, 5%, 0%, 0%; 25-30m, pile foundation suitability for 30-65m are suitable for the evaluation; the results for the The city planning of Shijiazhuang provides a powerful scientific basis.
