【摘要】:近年來,城市發(fā)展十分迅速,農(nóng)業(yè)斑塊不斷減少,本文通過對(duì)沈撫新城的景觀格局和生態(tài)適宜性進(jìn)行分析和探索,為此區(qū)域的都市農(nóng)業(yè)空間布局提供依據(jù),對(duì)沈撫新城的都市農(nóng)業(yè)進(jìn)行優(yōu)化,協(xié)調(diào)都市農(nóng)業(yè)發(fā)展和城市化、減小人為力量的沖擊、優(yōu)化都市農(nóng)業(yè)功能與城市化、將都市農(nóng)業(yè)景觀和城市景觀建設(shè)融為一體具有重要的意義。本論文里通過3S技術(shù),對(duì)沈撫新城研究區(qū)進(jìn)行景觀格局分析與生態(tài)適宜性分析,并以此為依據(jù)優(yōu)化構(gòu)建了都市農(nóng)業(yè)功能分區(qū),探討了生態(tài)控制分區(qū)、景觀景點(diǎn)策劃、道路交通規(guī)劃等。研究結(jié)果如下:(1)沈撫新城的景觀格局分析通過計(jì)算機(jī)的ArcGis軟件解譯沈撫新城2014年的衛(wèi)星影像圖,并通過Fragstats軟件計(jì)算景觀格局指數(shù),分析結(jié)果如下:沈撫新城的斑塊數(shù)目相對(duì)很少,破碎度低,不同斑塊種類的邊界特征相對(duì)復(fù)雜,斑塊的形狀也不規(guī)則,在景觀整體中關(guān)鍵景觀類型的比重很高,類型之間的能量和物質(zhì)移動(dòng)暢達(dá),整體景觀的多樣性很高。(2)沈撫新城的生態(tài)適宜性分析本文里主要從自然的角度來對(duì)研究區(qū)進(jìn)行生態(tài)適宜性分析,根據(jù)實(shí)際選擇了地形地貌、土壤侵蝕、地表水源、雨洪安全、植被覆蓋、生物保護(hù)六個(gè)要素,繪制六個(gè)要素因子的空間分級(jí)圖,按照相關(guān)因子在區(qū)域內(nèi)的重要程度,給予它們不同權(quán)值,利用GIS地理信息系統(tǒng)的空間運(yùn)算功能進(jìn)行因子堆疊,構(gòu)建自然生態(tài)要素的安全格局。(3)沈撫新城的都市農(nóng)業(yè)優(yōu)化在沈撫新城景觀格局及生態(tài)適宜性分析的基礎(chǔ)上,綜合借鑒景觀設(shè)計(jì)學(xué)理論,又要兼顧都市農(nóng)業(yè)的發(fā)展模式。結(jié)合自然條件、社會(huì)經(jīng)濟(jì)發(fā)展的現(xiàn)狀、生態(tài)控制格局分布,沈撫新城的都市農(nóng)業(yè)空間布局為一核兩翼一帶。以"連接三產(chǎn),融合三生"為主要發(fā)展策略,在生態(tài)保護(hù)的基礎(chǔ)上形成沈撫新城都市農(nóng)業(yè)的空間優(yōu)化。
[Abstract]:In recent years, the urban development is very fast, the agricultural patch is decreasing continuously. This paper analyzes and explores the landscape pattern and ecological suitability of Shenfu New City, and provides the basis for the spatial layout of urban agriculture in this area.It is of great significance to optimize the urban agriculture of Shenfu New City, coordinate the development of urban agriculture and urbanization, reduce the impact of artificial forces, optimize the function of urban agriculture and urbanization, and integrate the urban agricultural landscape and urban landscape construction.In this paper, through 3s technology, the landscape pattern and ecological suitability of Shenfu Xincheng research area are analyzed, based on which the urban agricultural function zoning is optimized, and ecological control zoning and landscape scenic spot planning are discussed.Road traffic planning, etc.The results of the study are as follows: 1) the landscape pattern of Shen Fu Xincheng is analyzed. The satellite image of Shenfu Xincheng in 2014 is interpreted by computer ArcGis software, and the landscape pattern index is calculated by Fragstats software.The results are as follows: the number of patches in Shenfu New Town is relatively small, the degree of fragmentation is low, the boundary characteristics of different patches are relatively complex, the shape of patches is irregular, and the proportion of key landscape types in the whole landscape is very high.The ecological suitability of Shenfu Xincheng is analyzed mainly from the natural point of view, and the topography and landform are selected according to the actual situation.Soil erosion, surface water sources, rain and flood safety, vegetation cover, biological protection, spatial classification of the six factor factors, giving them different weights according to the importance of the relevant factors in the region,On the basis of the analysis of landscape pattern and ecological suitability of Shenfu New Town, the security pattern of natural ecological elements was constructed by using the spatial operation function of GIS to build up the security pattern of natural ecological elements, and the urban agricultural optimization of Shenfu New Town was based on the analysis of landscape pattern and ecological suitability of Shenfu New Town.Comprehensive reference landscape design theory, but also to take into account the development model of urban agriculture.According to the natural conditions, the present situation of social and economic development, the distribution of ecological control pattern, the spatial distribution of urban agriculture in Shenfu Xincheng is one core and two wings.Based on the main development strategy of "connecting the three industries and integrating the three generations", the spatial optimization of urban agriculture in Shenfu Xincheng was formed on the basis of ecological protection.
