【摘要】：在我國社會經(jīng)濟快速發(fā)展的背景下,城市化進程的不斷推進導致城市生態(tài)斑塊日益減少,生態(tài)環(huán)境問題正在逐年增加,構建生態(tài)網(wǎng)絡是改善城市生態(tài)環(huán)境與服務功能的有效方法之一。以余江縣為研究區(qū),采用形態(tài)學空間格局分析(MSPA)方法和景觀指數(shù)法,提取對生態(tài)網(wǎng)絡具有重要意義的生態(tài)源地,并基于MCR模型構建綜合阻力面,采用最小成本路徑方法生成潛在廊道,再基于重力模型、中介中心度等對關鍵廊道及踏腳石斑塊進行識別并提取,從而構建研究區(qū)潛在生態(tài)網(wǎng)絡。結果表明:MSPA方法能夠與MCR模型有機的結合,通過定量的分析識別出研究區(qū)潛在生態(tài)廊道,并根據(jù)斑塊的中介作用選定踏腳石斑塊,明確研究區(qū)景觀要素的保護優(yōu)先度,將景觀中的潛在生態(tài)源地及廊道作為生態(tài)網(wǎng)絡構建的主要依據(jù),能夠更加科學地為余江縣生態(tài)網(wǎng)絡的構建提供指導,同時也可為其他區(qū)域提供參考。
[Abstract]:Under the background of the rapid development of our country's social economy, the continuous advancement of the urbanization process leads to the decreasing of the urban ecological plaque, and the ecological environmental problems are increasing year by year. Constructing ecological network is one of the effective methods to improve urban ecological environment and service function. Taking Yujiang County as the study area, the authors used morphological spatial pattern analysis and landscape index method to extract the ecological sources which are important to the ecological network, and constructed the comprehensive resistance surface based on the MCR model. The method of minimum cost path is used to generate potential corridors, and based on gravity model and intermediary center degree, the key corridors and steppe plaques are identified and extracted, so as to construct the potential ecological network of the study area. The results showed that the WMSPA method could be combined organically with the MCR model, and the potential ecological corridors in the study area could be identified by quantitative analysis, and the steppe plaque was selected according to the mediating effect of the patch, and the protection priority of landscape elements in the study area was determined. Taking the potential ecological source and corridor in the landscape as the main basis for the construction of ecological network can provide more scientific guidance for the construction of ecological network in Yujiang County and also provide reference for other regions.
