摘要:
根据实地调查,三峡库区开县前置库有维管植物116科307属410种(包括亚种、变种和变型),其中野生植物96科239属312种,国家保护植物5科5属5种.根据植物群落学-生态学原则,该区植被可划分为6个植被型,8个群系组,18个群系.因此该区的植物种类较贫乏,但栽培种类较多,约占总种数的1/4;植被的次生性质明显,主要为草丛和少量灌丛群落.根据该区的具体特征,提出开县前置库消落带的生态恢复应遵循工程措施与生物措施相结合、植被恢复为先导和生态位分化的原则.
Abstract:
By field survey, there are 410 species ( including subspecies, varieties, and forms) of vascular p lants in p re-dam of Kai Countywithin Three Gorges Reservoir. Among them, wild p lants are 312 species in 239 genera of 96 families, and five of these species are the rare and endangered p lants p rotected by the law in China. Itsmain vegetation types are classified into 18 formations, belonging to 8 formation group s and 6 vegetation types based on the p lant community-ecology p rincip le. Therefore, its p lant species are relatively poor although the cultivated p lants app roximately account for a quarter of total species in this ar ea; those vegetations, which aremainly composed of grasslands and a few shrublands, havemarkedly sec ondary characteristics because of man-made disturbance. In addition, the ecological rehabilitation about water-level-fluctuating zone in this area should be on the p rincip les such as combination of engineering measures with biological ones, vegetation recovery as p riovity, and niche differentiation based on its char acters of p lant diversity.
