【摘要】：城市公園綠地是城市綠地系統(tǒng)的重要組成部分,同時(shí),也是城市居民重要的公共游憩場(chǎng)所。居民能否方便快捷進(jìn)入公園,以實(shí)現(xiàn)這一綠色公共設(shè)施的使用,是衡量城市宜居水平的重要指標(biāo)。我國(guó)現(xiàn)行的城市綠地評(píng)價(jià)指標(biāo)體系主要關(guān)注城市綠地率、人均公園面積等針對(duì)于綠地的 量‖的衡量,對(duì)公園綠地的布局合理性、居民到達(dá)公園的便捷性等方面仍缺少定性與定量的分析與評(píng)價(jià)。公園綠地可達(dá)性能較好反映它為居民提供服務(wù)的可能性和潛力,其作為評(píng)價(jià)城市綠地建設(shè)的新指標(biāo),已得到廣泛認(rèn)可。按照網(wǎng)絡(luò)特性的差異,可以將可達(dá)性分為幾何網(wǎng)絡(luò)和拓?fù)渚W(wǎng)絡(luò)兩大類。目前,用于公園綠地可達(dá)性的評(píng)價(jià)方法,主要是基于幾何網(wǎng)絡(luò)的度量方法�；谕�?fù)渚W(wǎng)絡(luò)的可達(dá)性,空間結(jié)構(gòu)形態(tài)所致的人流、物流、信息流等潛在運(yùn)動(dòng)密度分布,考慮了心理可達(dá)性,可以從新的角度補(bǔ)充公園綠地可達(dá)性的評(píng)價(jià)系統(tǒng)。本文借助“空間句法”的理論和方法,從拓?fù)渚W(wǎng)絡(luò)角度,創(chuàng)新現(xiàn)有的公園可達(dá)性研究思路,并借助Depthmap、GIS、ENVI以及SPSS等軟件分析平臺(tái),對(duì)城市公園綠地的拓?fù)淇蛇_(dá)性進(jìn)行量化分析研究,探求城市公園綠地的社會(huì)服務(wù)能力與其空間分布形態(tài)之間的內(nèi)在聯(lián)系。論文通過武漢城市模型以及公園句法模型的建立、驗(yàn)證以及變量指標(biāo)分析,對(duì)武漢市綜合性公園的句法可達(dá)性進(jìn)行綜合評(píng)價(jià),并得出以下結(jié)論:根據(jù)公園句法模型值,將武漢市綜合性公園句法可達(dá)性分為6級(jí),其中,可達(dá)性等級(jí)最高的是中山公園、小南湖公園、寶島公園,其緩沖區(qū)內(nèi)路網(wǎng)的局部整合度(R2000)平均值均在140以上,可達(dá)性等級(jí)最低的是小磨山公園以及馬鞍山森林公園;總的來說,武漢市綜合性公園在空間結(jié)構(gòu)上的布局較為合理,首先,85%以上的公園位于全市模型中高可達(dá)性區(qū)域;其次,而空間拓?fù)淇蛇_(dá)性較高的公園,呈現(xiàn)集中分布的趨勢(shì),分布于漢口核心片區(qū);最后,綜合性公園的句法可達(dá)性的等級(jí)分布,與武漢市城市人口密度的等級(jí)分布,以及城市熱島效應(yīng)的等級(jí)分布,都保持較高的一致性。但是,部分整合度較高的活力次中心區(qū)域,無可達(dá)性較高的綜合性公園輻射,少數(shù)公園的入口沒有很好的結(jié)合周邊高可達(dá)性的路網(wǎng),還有待優(yōu)化改善。
[Abstract]:Urban park green space is an important part of urban green space system, and it is also an important public recreation place for urban residents. It is an important index to measure the livable level of the city whether the residents can enter the park conveniently and quickly to realize the use of the green public facilities. The current evaluation index system of urban green space in our country is mainly concerned with the measurement of urban green space rate, per capita park area and so on, and the rationality of the layout of park green space. There is still a lack of qualitative and quantitative analysis and evaluation on the convenience of residents to the park. The reachability performance of park green space reflects the possibility and potential of providing service to residents, and it has been widely accepted as a new index to evaluate the construction of urban green space. According to the difference of network characteristics, reachability can be divided into geometric network and topological network. At present, the method of evaluating the accessibility of park green space is mainly based on geometric network. Based on the distribution of potential motion density such as the reachability of topological network, the form of spatial structure, the flow of people, logistics and information, the psychological reachability is considered, which can be used to supplement the evaluation system of the accessibility of park green space from a new angle. In this paper, with the help of the theory and method of "space syntax", from the point of view of topological network, this paper innovates the existing research ideas of park accessibility, and makes a quantitative analysis and research on the topological accessibility of urban park green space by means of the software analysis platform such as Depthmapper GISENVI and SPSS. To explore the internal relationship between the social service ability of urban park green space and its spatial distribution form. Through the establishment, verification and variable index analysis of Wuhan city model and park syntactic model, this paper comprehensively evaluates the syntactic accessibility of Wuhan comprehensive park, and draws the following conclusions: according to the value of park syntactic model, The syntactic reachability of Wuhan comprehensive park is divided into 6 levels. The highest degree of accessibility is Zhongshan Park, Xiaonanhu Park and Baodao Park. The average value of local integration of the network in its buffer area is above 140. The lowest degree of accessibility is Xiaomoshan Park and Ma'anshan Forest Park. In general, the spatial structure of Wuhan Comprehensive Park is more reasonable. First, more than 85% of the parks are located in the high reachability area of the whole city model; secondly, However, the parks with higher spatial topological accessibility show a tendency of concentrated distribution, which is distributed in Hankou core area. Finally, the syntactic accessibility grade distribution of comprehensive parks is similar to that of urban population density in Wuhan. And the grade distribution of urban heat island effect is consistent. However, some of the active sub-central areas with higher integration degree, there is no comprehensive park radiation with higher accessibility, and a few parks do not have a good access to the surrounding high-accessibility road network, which needs to be optimized and improved.
