自然保护区面积

自然保护区面积13295万公顷，占国土总面积的13.2%。

人类活动对外来入侵植物的扩散具有明显的影响，其中交通密度、农作物播种面积具有较强正相关关系；自然保护区面积、人口密度具有较强的负相关关系。

Human activities external to the spread of invasive plants has obvious impact , traffic density , crop acreage is a strong correlation between the nature reserve area , population density has strong negative correlation .

但是，发展至今也逐渐暴露出了严重的问题，即随着自然保护区面积的增加，保护区内的生物多样性却仍旧不断减少，这一现象不禁让人反思当下的自然保护区管理制度。

However , development has gradually revealed a serious problem that , with the increase in area of nature reserves , protected areas of biodiversity is still declining , a phenomenon that can not help but reflect on the present nature reserve management system .

迄至1987年，全国共载录有481处自然保护区，总面积约为23×10~6公顷，约占我国国土陆地面积的2.5%。

发展趋势上我国国家级自然保护区数量和面积增长率呈现逐年下降趋势，其发展趋势由数量向质量的方向转变。

Recently , the rate of increase of the number and the area national nature reserves has declined . It indicated that the development trend was changing quantity to quality .

The nature reserves cover 5 . 74 % of the total area in the Yangtze Basin , which is 1 . 9 % lower than the overall mean rate in China .

其中，森林生态类型自然保护区在数量与面积上占的比重最大，是陆地生态系统最典型、最复杂的生物多样性区域，最大的碳贮库，也是人类社会经济发展的基本保障。

Among them , the forest ecosystem type accounting for the largest share in the number and nature reserve area is the most typical terrestrial and complex areas of biodiversity , the largest reservoir for carbon , and the basic human security to the social and economic development .
