    摘要:

    以內(nèi)蒙古荒漠綠洲區(qū)為研究區(qū),將復雜網(wǎng)絡與潛在生態(tài)網(wǎng)絡進行類比分析,研究生態(tài)系統(tǒng)能量流動的特征,分析潛在生態(tài)網(wǎng)絡的關(guān)聯(lián)性、完整性和穩(wěn)定性。結(jié)合相應生態(tài)因子,構(gòu)建生態(tài)阻力面,提取潛在生態(tài)廊道1103條、生態(tài)節(jié)點992個。潛在生態(tài)網(wǎng)絡度分布符合冪律分布,因此,可將賦權(quán)網(wǎng)絡適配到潛在生態(tài)網(wǎng)絡進行分析。結(jié)果表明,荒漠綠洲區(qū)潛在生態(tài)網(wǎng)絡連通性較差,聚類特征不明顯;生態(tài)節(jié)點分布較為分散且破碎,完整性偏低;潛在生態(tài)網(wǎng)絡內(nèi)部能量流動情況較為單一,不夠穩(wěn)定。荒漠綠洲區(qū)內(nèi)生態(tài)景觀破碎化,發(fā)展與生態(tài)保護的矛盾較為突出,整體生態(tài)環(huán)境亟待優(yōu)化。

    Abstract:

    Taking the Inner Mongolia Desert Oasis as a research area, the analogy analysis of complex networks and potential ecological networks was carried out to study the characteristics of ecosystem energy flow and analyze the connectivity, integrity and stability of potential ecological networks. Combined with the corresponding ecological factors, the ecological resistance surface was constructed, and 1103 potential ecological corridors and 992 ecological nodes were extracted. The potential ecological network distribution was consistent with the power law distribution, so the weighted network can be adapted to the potential ecological network for analysis. The potential ecological network connectivity in the desert oasis area was poor, the clustering characteristics were not obvious; the ecological nodes were scattered and fragmented, and the integrity was low; the energy flow inside the potential ecological network was relatively simple and not stable enough. The ecological landscape in the desert oasis area was fragmented, and the contradiction between development and ecological protection was more prominent. The overall ecological environment needed to be optimized.
