    摘要:

    以景觀質(zhì)量和生態(tài)質(zhì)量構(gòu)建了包含8個(gè)指標(biāo)的景觀生態(tài)質(zhì)量評(píng)價(jià)指標(biāo)體系;基于GIS及GeoDa平臺(tái),采用層次分析法(AHP)與均方差決策法的混合模型確定權(quán)重,從等級(jí)劃分和指數(shù)差研究了2005—2010年巢湖流域快速城鎮(zhèn)化背景下景觀生態(tài)質(zhì)量在村莊尺度的時(shí)空演變特征,采用空間自相關(guān)法分析其空間分異與聚集特征,并提出了相應(yīng)的生態(tài)規(guī)劃建議。結(jié)果表明:2005—2010年巢湖流域景觀生態(tài)質(zhì)量整體以穩(wěn)定不變型為主,但其局部退化程度較改善程度在村莊數(shù)量占比和面積比方面分別提高了28.61%和29.90%;整體呈現(xiàn)研究區(qū)西部改善而北、東和南部退化的空間格局。從景觀生態(tài)質(zhì)量指數(shù)差方面,2010年的景觀生態(tài)質(zhì)量較2005年退化的面積占研究區(qū)的78.65%,在研究區(qū)北部、東北部、東部及南部密集分布和西部零星分布。2005年景觀生態(tài)質(zhì)量為較強(qiáng)的空間集聚性,2005—2010年景觀生態(tài)質(zhì)量變化隨時(shí)間推移而空間集聚性減弱。根據(jù)兩期的高高區(qū)、低低區(qū)及低高或高低區(qū)的特征分區(qū),并在生態(tài)用地保護(hù)、產(chǎn)業(yè)布局優(yōu)化、土地用途與低效工業(yè)用地管制、綠色基礎(chǔ)設(shè)施與生態(tài)廊道的規(guī)劃建設(shè)等方面提出了相關(guān)生態(tài)規(guī)劃建議。研究結(jié)果可為區(qū)域生態(tài)景觀規(guī)劃、生態(tài)管護(hù)及景觀生態(tài)系統(tǒng)的可持續(xù)發(fā)展提供科學(xué)借鑒。

    Abstract:

    Regional landscape ecological quality assessment and research of its spatial and temporal differentiation would help to locate regional ecological function, optimize resource allocation and maintain regional sustainable development. The evaluation index system of landscape ecological quality was constructed on the basis of landscape quality and ecological quality, which covered eight comprehensive indexes. Based on GIS and GeoDa platform, the weight of indexes were determined by using the mixed model of AHP and mean variance decision method, the spatiotemporal evolution characteristics of the landscape ecological quality were studied in the village of Chaohu Basin during 2005—2010 in the context of rapid urbanization from the aspects of gradation and index difference, the spatial autocorrelation method was used to analyze the spatial differentiation and aggregation characteristics and the corresponding ecological planning suggestions were put forward. The results showed that the landscape ecological quality in the Chaohu Basin was mainly stable in 2005—2010, but its local degradation was 28.61% and 29.90% respectively higher than that of improvement in ratio of villages’ number and area, in which the western part of the study area was improved and the north, east and south parts were degraded. From the index difference of landscape ecological quality, the degraded area of landscape ecological quality in 2010 accounted for 7865% of the study area compared with 2005, and distributed densely in the north, northeast, east and south of the study area and sporadically in the west. The spatial agglomeration of landscape ecological quality, which was stronger in 2005, was decreased with time from 2005 to 2010. According to the characteristic zoning of high-high, low-low, high-low and low-high zones in the two phases, some related planning suggestions were put forward in the aspects of ecological land protection, industrial layout optimization, land use and low efficiency industrial land control, green infrastructure and ecological corridor. The research results can provide a scientific reference for the regional ecological landscape planning, ecological management and protection, and the sustainable development of landscape ecosystem.
