我国对生物多样性进行就地保护的区域除自然保护区之外,同样具有保护功能的还有森林公园、湿地公园、风景名胜区和地质公园等,均可归入到保护地的范畴。目前我国保护地数量很多,但由于各类保护地分属于不同部门管理,缺乏统一规划,布局不合理。本文运用ArcGIS9.3分析软件建立实点坐标数据库及分布图,结合地理集中指数、不平衡指数、基尼系数和综合密度指数,探讨自然保护区、风景名胜区、森林公园、湿地公园和地质公园这5种主要保护地的空间分布格局。结果表明,自然保护区与风景名胜区、森林公园、湿地公园和地质公园在整体空间分布上极为相似,均呈现集中分布且不均衡,东部密集、西部稀疏; 但它们在不同省份及行政区域的分布又具有差异性。风景名胜区、森林公园、湿地公园和地质公园有效补充了自然保护区的面积局限性,丰富了我国保护地体系,对自然资源保护有辅助作用。

Opuntia humifusa (Raf.)Raf.(Cactaceae), a newly recorded species in China, was discovered during a survey of succulent resources. This species is distinct from other Opuntia species distributed in China, with the dark green prostrate cladodes, no glaucous, spines absent, and bright yellow flowers. O. humifusa is one of the few hardy species in the family Cactaceae. It is native to North America and has been recently naturalized in Wulian County, Rizhao City, Shandong Province, China. It is the northernmost wild cactus found in China. This species might have been introduced and planted during the national promotion of Chinese herbal medicine in the 1950s, and gradually spreaded through human activities. Here we clarify the taxonomic problems of O. humifusa and O. cespitosa in Jiangsu Province, and deliver perspective views for future reasonable development and utilization of O. humifusa in the warm temperate zone of China.

The purpose of this study was to explore the structural and expression characteristics of LEA2 genes from Brachymenium exile. BeLEA2 gene was firstly isolated and analyzed by polymerase chain reaction(PCR). The results were as follows:(1)Gene structure analysis showed that BeLEA2 gene contained 2 exons and 1 intron and contained an open reading frame(ORF)of 456 bp encoding a protein of 151 amino acids, and its molecular mass was predicted to be 16 515.96 Da.(2)The phylogenetic analysis of LEA2 with other LEA2 in different plants revealed that BeLEA2 from B. exile and LEA2 from Physcomitrella patens belonged to the same branch of evolutionary distance.(3)The promoter sequence of the BeLEA2 gene of 1 072 bp was isolated from Brachymenium exile by high-efficiency hermal asymmetric interlaced polymerase chain reaction (HiTail-PCR) and analyzed by PlantCARE, the results showed that it had TATA-box, CAAT-box, ABRE, MYB, MYC, MYB binding site and other cis-acting elements.(4)Quantitative real-time PCR analysis indicated that BeLEA2 expressed in different stages and tissues of B. exile, and BeLEA2 responded to dehydration stress. These results lay a foundation for further study on the function of LEA2 gene in bryophytes. [ABSTRACT FROM AUTHOR]
