【摘要】：基于计算机模型的湿地公园规划具有低成本、高效率、多情景等优点,可以为规划研究提供初步方案的评优和选择。将CLUE-S模型运用到湿地公园规划中,结合生态保护情景和旅游开发情景的设定,对新济洲湿地公园进行2020年景观格局模拟预测,最后从湿地鸟类穿越的最小累积阻力模型角度,对两种情景进行了比较分析,得出如下结论:(1)对CLUE-S模型在研究区的适用性进行验证,经过计算,模拟的精度检验指数Kappa值为0.763,表明CLUE-S模型用来做新济洲湿地公园景观格局变化的预测模型具有良好的可靠性;(2)土壤有机质含量是推动新济洲湿地公园景观变化的最重要驱动因子,其影响力度远远高于其他因子;(3)通过建立MCR模型可以发现,两种情景都具有各自的优缺点,对于生态保护情景需要注意的是拓宽湿地鸟类穿越廊道,减少最小累积阻力路线生态缓冲区内的人为干扰。而对于旅游开发情景来说,构建整体的生态串联性则显得尤为重要,需要在中部大阻力区域为湿地鸟类穿越开辟一条良好的保护通道。
[Abstract]:The computer model based on the planning of Wetland Park has the advantages of low cost, high efficiency, multi scene etc., can provide a preliminary planning study program evaluation and selection. The CLUE-S model is applied to wetland park planning, combined with ecological protection scenario and tourism development situation, predict 2020 landscape pattern of Xinjizhou wetland, minimum from the angle of the cumulative resistance model of wetland birds across, two scenarios were analyzed. The conclusions are drawn as follows: (1) to verify the applicability of CLUE-S model in the study area, through calculation, accuracy test index Kappa simulation show that the prediction value was 0.763, the CLUE-S model used to make changes in wetland landscape the new pattern of Jeju has good reliability; (2) the content of soil organic matter is the most important driving factor to promote the Xinjizhou wetland landscape changes, its impact strength Is far higher than other factors; (3) through the establishment of MCR model can be found, two scenarios have their respective advantages and disadvantages, the need to pay attention to the ecological protection scenario is to broaden the wetland birds across the corridor, reducing humaninterferences minimum cumulative resistance line ecological buffer zone. And for the tourism development situation, it is very important the construction of the overall ecological series, need in the central region for wetland birds through resistance provides a good protection channel.

【正文快照】： 作为全球生态系统之一的湿地,具有保持水源、净化水质、合理调节气候、维护生态平衡等一系列功能[1]。然而,20世纪中后期由于人为破坏,湿地面积严重萎缩,导致一系列生态问题,如水质下降、生物多样性降低、湿地功能丧失等等。目前这一问题已逐步得到重视。然而,由于湿地系统的
