【摘要】：本研究以廣州市城市綠色空間為研究對象,通過3S技術(shù)和室外實地觀測調(diào)查方法,探討城市綠色空間的格局破碎度、斑塊大小和均衡性特征,以及量化綠色空間的降溫增濕、滯塵凈氣等生態(tài)服務(wù)功能特征;同時結(jié)合問卷調(diào)查和實地觀察的方式度量居民對城市綠色空間的認(rèn)知、環(huán)境改善的支付意愿和完善建議等社會文化服務(wù)功能特征。旨在為今后的城市合理規(guī)劃、政府高效管理、綠色空間科學(xué)建設(shè)提供科學(xué)依據(jù)和研究案例。主要研究結(jié)論如下:(1)在1979~2014年,廣州城市綠色空間面積比例呈階段性起伏(增大-減小-再增大-再減小)變化特征,空間格局更加破碎化和復(fù)雜化,以小型和特小型斑塊為主導(dǎo)的破碎化格局。綠色空間格局均衡性等級面積百分比呈“W”型曲線特征,服從四項多項式函數(shù)分布規(guī)律。2000年以來,綠色空間格局均衡性等級呈兩極分化的特征,區(qū)域差異明顯(如番禺、南沙和中心城區(qū)等)。(2)城市綠色空間斑塊面積越大,其降溫和增濕效果越好(如白云山)。其中,中午(12:00~13:00pm)降溫幅度最大,早上(8:00~10:00 am)增濕幅度最大,早上(6:00~10:00am)滯塵凈氣效果明顯。不同綠色空間類型的生態(tài)服務(wù)功能特征差異明顯,降溫效果:喬木≈2×草地≈4×灌木,增濕效果:喬木≈2×灌木≈4×草地,草地類型滯塵波動變化較為敏感。(3)大部分居民對廣州城市綠化印象較好,且認(rèn)識到綠色空間對改善環(huán)境質(zhì)量的重要性。由相關(guān)性和回歸模型分析可知,不同典型綠色公園間居民的認(rèn)知特征差異明顯,且與被調(diào)查者的社會經(jīng)濟背景和個人特征等因素有關(guān),如年齡、月收入水平達(dá)到顯著正相關(guān)水平。條件價值法評估居民對綠色空間環(huán)境改善的支付意愿仍處于觀望階段,支付意愿與受教育程度、收入水平及接觸綠色空間的容易程度等因素有關(guān)。不同類型的城市綠色公園有各自的完善建議,具有針對性和建設(shè)性的特征。從“格局與功能”兩大方面分析廣州城市綠色空間特征,研究結(jié)論有助于政府了解哪些因素影響居民對綠色空間的態(tài)度和實際需求,同時有利于今后城市合理規(guī)劃、綠色空間科學(xué)布局、政府高效管理及城市可持續(xù)發(fā)展提供一定的科學(xué)依據(jù)和研究案例。
[Abstract]:Taking the urban green space of Guangzhou as the research object, the pattern fragmentation degree, patch size and equilibrium characteristics of urban green space were discussed by 3s technology and outdoor field survey method, and the cooling and humidification of green space were quantified. At the same time, the characteristics of social and cultural services such as residents' cognition of urban green space, willingness to pay for environmental improvement and suggestions for improvement were measured by means of questionnaire survey and field observation. The purpose of this paper is to provide scientific basis and research case for urban rational planning, efficient management of government and construction of green space science in the future. The main conclusions are as follows: (1) from 1979 to 2014, the proportion of green space area in Guangzhou city showed the characteristics of periodic fluctuation (increase, decrease, increase and decrease), and the spatial pattern was more fragmented and complicated. Fragmentation pattern dominated by small and especially small patches. The area percentage of equilibrium grade of green spatial pattern shows the characteristic of "W" curve and the distribution law of four polynomial functions. Since 2000, the equilibrium grade of green spatial pattern has been polarized, and the regional differences are obvious (for example, Panyu, Panyu, Panyu, Panyu, Panyu, Panyu, Panyu). The larger the green patch area in Nansha and the central urban area, the better the effect of cooling and humidifying (such as Baiyun Mountain). Among them, 12: 00: 13: 00 pm) the temperature drop is the largest, 8: 00: 10: 00 am is the most humid, and 6: 00 10: 00 am in the morning. The characteristics of ecological service function of different green space types were obviously different. The cooling effect was as follows: Arbor 鈮，
