大熊猫国家公园(四川片区)景观多样性与物种多样性的关联性研究

为提升生物多样性监测能力，探索利用遥感手段开展生物多样性监测的可行性，笔者采用空间制图、冗余分析(RDA)等技术方法探究大熊猫国家公园（四川片区）生物多样性在景观尺度（景观多样性）与物种尺度（物种丰富度）的关联性。结果表明:(1) 大熊猫国家公园（四川片区）的物种多样性整体较高，高值区主要位于中南部的宝兴县、天全县和汶川县。这一区域植物共计231科1 302属5 675种，动物共计39目141科1 049种。(2) 大熊猫国家公园（四川片区）的景观多样性整体较高，其中，北部高于南部，靠近川西北高山峡谷一侧高于成都平原一侧。(3)景观多样性对物种多样性的模型解释率可达41.64%。物种多样性与景观指数PR、ENN_SD具有强正相关，与PRD具有强负相关。景观多样性与物种多样性存在较高的相关性。建议进一步加强生物多样性物种本底调查，整合现有各类物种、遗传资源数据库，以尽快摸清家底，为大熊猫国家公园建设提供客观政策建议；进一步深入开展景观多样性与物种多样性关联研究，探索利用遥感技术，从景观尺度动态监测生物多样性的变化。

Relationship between Landscape Diversity and Species Diversity in Sichuan Area of Giant Panda National Park

Biodiversity monitoring is the core basis for the protection of ecosystem integrity and authenticity in national parks. In order to improve the ability of biodiversity monitoring and explore the feasibility of application of remote sensing in biodiversity monitoring, the relationship between biodiversity at landscape and species scale in Giant Panda National Park (Sichuan area) was analyzed by using spatial mapping, redundancy analysis (RDA) and other technical methods. The results showed that the species diversity of the Giant Panda National Park (Sichuan area) was generally higher, especially in Baoxing, Tianquan and Wenchuan counties. The park boasts of 5675 species of plants belonging to 1302 genera and 231 families, and 1049 species of animals belonging to 141 families and 39 orders. The landscape diversity of the Giant Panda National Park (Sichuan area) is higher in the north than in the south, and higher in the mountain valley near the northwest of Sichuan than in the Chengdu plain. The model interpretation rate of landscape diversity on species diversity was 41.64%. Species diversity had a high positive correlation with landscape indices the patch richness (PR) and the standard deviation of Euclidean nearest neighbor distance (ENN_SD), and a high negative correlation with the patch richness density (PRD). It is suggested to give full play to the advantages of remote sensing technology to strengthen the dynamic monitoring of the biodiversity in the Giant Panda National Park at the landscape scale. It is also suggested to further strengthen the baseline inventory of biodiversity species and integrate the existing databases of various species and genetic resources so as to find out the resources as soon as possible and provide objective policy suggestions for the construction of the Giant Panda National Park.
