【摘要】:在社會公眾戶外游憩需求規(guī)模日益擴(kuò)大的背景下,城市森林游憩功能的重要意義愈加凸顯。森林游憩是國民休閑旅游的重要組成部分,城市森林游憩功能開發(fā)是城市生態(tài)建設(shè)的重要內(nèi)容。城市森林游憩功能提升和管理決策的關(guān)鍵是評價與診斷不同時空尺度的城市森林游憩適宜性。本研究以上海城市森林為研究對象,共選擇林地64片,通過構(gòu)建城市林游憩適宜性評價指標(biāo)體系,在解析2000、2006和2012年上海城市森林景觀動態(tài)變化的基礎(chǔ)上,探究了城市森林游憩適宜性的動態(tài)變化及其演變規(guī)律。主要結(jié)論如下:(1)上海城市森林各景觀類型動態(tài)變化總體特征為:各年份景觀類型中面積最大的均為植被。景觀類型的變化趨勢中,各類景觀類型的變化趨勢中,植被的變化隨著年份的增加呈增加趨勢;水體、道路的變化,從2000到2006年均增加,從2006到2012年均減少,此二種類型2000到2012年總的變化趨勢是減少;住宅建筑2000至2006年減少,2006至2012年增加,2000至2012年總變化減少;管理服務(wù)設(shè)施的變化從2000到2006均增加,從2006到2012均減少,但2000到2012年的總變化趨勢是增加;景觀設(shè)施、游憩場地和農(nóng)田隨年份呈增加趨勢。景觀動態(tài)變化速率為,增長速率最快為景觀設(shè)施,其次是植被;減少速率最快為游憩場地和農(nóng)田。(2)構(gòu)建了由游憩資源、游憩服務(wù)設(shè)施和游憩區(qū)位三個方面,由景觀類型多樣性、植被覆蓋率、水體比例、游憩場地比例、管理服務(wù)設(shè)施比例、景觀游憩設(shè)施比例、到主要道路距離、到居民點(diǎn)距離、到周邊游憩景點(diǎn)距離十個指標(biāo)組成的城市森林游憩適宜性評價體系。并依據(jù)得分將游憩適宜性劃分為四個等級,由高至低分別為:最適宜、中度適宜、勉強(qiáng)適宜和不適宜。(3)2000年至2012年間,64片城市森林的游憩適宜性發(fā)生顯著變化。2000年多數(shù)城市森林為勉強(qiáng)適宜和中度適宜,分別為36和20個,面積占比為51.93%和34.76%。2006年,城市森林游憩適宜性顯著提高,主要集中在最適宜、中度適宜和勉強(qiáng)適宜3個等級,分別為19、29和14個,面積占比為34.84%、45.84%和19.16%。2012年,最適宜城市森林個數(shù)增加至33個,但面積占比小幅下降,為30.38%;同時,中度適宜個數(shù)為增加至24個,面積占比增至 53.95%。(4)比較64片城市森林中4種不同類型森林(森林公園、生態(tài)片林、外環(huán)公園、外環(huán)片林)發(fā)現(xiàn):2000年至2012年,除生態(tài)片林均維持在中度適宜等級之外,其他三類森林均呈逐漸增加趨勢,其中,森林公園平均適宜性等級逐漸增加,由勉強(qiáng)適宜等級增至最適宜等級,外環(huán)公園由中度適宜等級增至最適宜等級,外環(huán)片林由不適宜增加至最適宜等級。
[Abstract]:Under the background of the increasing scale of public outdoor recreation demand, the significance of urban forest recreation function is becoming more and more prominent. Forest recreation is an important part of national leisure tourism, and the development of urban forest recreation function is an important part of urban ecological construction. The key to the promotion of urban forest recreation function and the decision of management is to evaluate and diagnose the suitability of urban forest recreation with different spatial and temporal scales. Taking Shanghai urban forest as the research object, 64 pieces of woodland were selected in this study. Based on the analysis of the dynamic changes of urban forest landscape in 20002006 and 2012, the evaluation index system of urban forest recreation suitability was constructed. The dynamic change and evolution law of urban forest recreation suitability were studied. The main conclusions are as follows: (1) the general characteristics of the dynamic changes of the landscape types of urban forests in Shanghai are as follows: vegetation is the largest landscape type in each year. In the changing trend of landscape type, in the change trend of all kinds of landscape type, the change of vegetation is increasing with the increase of year, the change of water body and road increases annually from 2000 to 2006, and decreases from 2006 to 2012. The overall trend of change between 2000 and 2012 for these two types is decreasing; residential buildings decreased from 2000 to 2006 and increased from 2006 to 2012; and changes in management services increased from 2000 to 2006 and decreased from 2006 to 2012, respectively. However, the total change trend from 2000 to 2012 was increased, and landscape facilities, recreation sites and farmland showed an increasing trend with the year. The dynamic change rate of landscape is: the fastest growth rate is landscape facilities, followed by vegetation, and the fastest reduction rate is recreation site and farmland. (2) the diversity of landscape types is based on recreation resources, recreation service facilities and recreation location. Vegetation coverage, water body ratio, recreation site ratio, management service facility ratio, landscape recreation facility ratio, distance to main road, distance to residential area, The evaluation system of urban forest recreation suitability is composed of ten indexes. According to the score, the recreation suitability was divided into four grades, from high to low, which were the most appropriate, the moderate suitability. Between 2000 and 2012, the recreational suitability of 64 urban forests changed significantly. In 2000, most urban forests were barely and moderately suitable, 36 and 20, respectively, with an area of 51.93% and 34.76.2006, respectively. The suitability of urban forest recreation was significantly improved, mainly concentrated in the most suitable, moderate and barely suitable three grades (1929 and 14, respectively). The proportion of area to area was 34.8445.84% and 19.16.2012, and the number of the most suitable urban forest increased to 33. But the proportion of area decreased slightly to 30.38. At the same time, the number of moderately suitable forests increased to 24, and the proportion of area increased to 53.95.Qu4.) four different types of forests (forest park, ecological forest, outer ring park) were compared among 64 urban forests. From 2000 to 2012, all the other three types of forests showed an increasing trend except that the ecological forest was maintained in the moderate suitability grade, and the average suitability grade of the forest park increased gradually, and the average suitability of the forest park increased gradually from 2000 to 2012. From the barely appropriate grade to the most suitable grade, the outer ring park increased from the moderate to the most suitable level, and the outer ring forest increased from the unsuitable to the most suitable grade.
