準公共物品視角下的城市公園綠地評價與優(yōu)化研究
發(fā)布時間:2018-08-26 17:16
【摘要】:改革開放以來,我國市場經濟體制改革不斷深化。公園綠地作為城市公共服務的空間載體之一,其空間布局面臨著多重挑戰(zhàn):一方面,公園綠地需要在受到土地與資金的雙重制約下進行開發(fā)建設以改變我國公園綠地服務水平普遍低下的現(xiàn)狀;另一方面,作為城市公共服務的載體,在使用過程中又要面對市民日益多元的訴求。在此背景下,如何合理、有效地對公園綠地進行空間配置就成為了難題。傳統(tǒng)研究主要以可達性方法對公園綠地空間布局進行評價,忽視了公園綠地在使用過程中存在的競爭性與排他性。因此本研究以國家園林城市—紹興為例,基于GIS技術,從可達性方法與準公共物品視角兩個層面展開公園綠地服務范圍評價實證研究。在對公園綠地空間布局不合理的原因進行剖析的基礎上,從政策與空間兩個維度提出評價區(qū)域公園綠地空間布局優(yōu)化策略。 本研究得出主要結論如下:(1)傳統(tǒng)可達性評價方法忽視了公園綠地使用過程中的競爭性與排他性,因此在表征公園綠地空間分布公平性方面具有較大局限性;(2)傳統(tǒng)可達性方法與非競爭性、非排他性準則下的評價結果相比,呈現(xiàn)出較大差異性;(3)評價區(qū)域內公園綠地使用過程中存在著多重矛盾,公共資源過度利用與非充分利用的尷尬局面并存;(4)盲目地將公共資源“完全公共物品”化,不僅加重了公共財政負擔,且易形成更大空間范圍內的不公平現(xiàn)象;(5)市場經濟環(huán)境下,公園綠地空間布局合理化的關鍵在于建立多方參與的供給機制以及靈活的運營機制,在這—過程中需要相關政策的不斷優(yōu)化。
[Abstract]:Since reform and opening up, our country market economy system reform deepens unceasingly. As one of the space carriers of urban public service, park green space faces many challenges: on the one hand, The park green space needs to be developed and constructed under the dual restriction of land and capital to change the status quo of the generally low level of park green space service in our country; on the other hand, as the carrier of urban public service, the park green space should be developed and constructed under the dual restriction of land and capital. In the process of use, we have to face the increasingly diverse demands of the public. In this context, how to rationally and effectively allocate the park green space has become a difficult problem. The traditional research mainly uses the reachability method to evaluate the space layout of the park green space, neglecting the competition and exclusiveness in the process of using the park green space. Therefore, taking Shaoxing, a national garden city, as an example, based on GIS technology, an empirical study on the evaluation of green space service range is carried out from the perspectives of accessibility method and quasi-public goods. On the basis of analyzing the reason of unreasonable space layout of park green space, this paper puts forward the optimization strategy of evaluating the space layout of regional park green space from the two dimensions of policy and space. The main conclusions of this study are as follows: (1) the traditional method of accessibility evaluation ignores the competition and exclusivity in the process of using park green space, so it has great limitations in characterizing the fairness of the spatial distribution of park green space; (2) the results of traditional reachability method are different from those under non-competitive and non-exclusive criteria, and (3) there are many contradictions in the process of using park green space in the evaluation area. (4) blindly turning public resources into "complete public goods" not only increases the burden of public finance, but also easily forms the unfair phenomenon in a larger space; (5) under the market economy environment, the key to the rationalization of the space layout of the park green space lies in the establishment of multi-party supply mechanism and flexible operation mechanism. In this process, the related policies need to be optimized continuously.
