林地生长数据 Forest Growth Data

2017年百万植树计划继续与灵武市白芨滩防沙林场合作,在白芨滩保护区大柳毛子风沙区展开,总面积为一千亩,总计栽植约二十万余株。主要种植的种类为柠条,另有少量沙拐枣。由于沙拐枣数量不多并且只作为先锋植物使用,2017宁夏林地中测量的主要物种为柠条。在2019年,2017-NX林地的柠条总存活率为55.25%,均高88.12厘米,平均半径为24.23厘米。林地平均种植密度为416/亩,存活密度为229/亩,已经远超180/亩的种植目标。

Working with Baijitan Tree Farm, we continued our desert control effort in 2017. The reforestation site is located at Daliumaozi sand area, Baijitan Nature Reserve, Lingwu, Ningxia. Over 200,000 shrubs have been planted, covering a total area of 66.7 hectares. The major kind of what we planted in the site is Caragana, and a number of Calligonum were also planted. But this small number of Calligonum were supposed to be pioneer species. We collect data only about Caragana. In year 2018, the total survival rate of Caragana in 2017-NX forest site is 55.25%. The average height is 88.12cm and average radius is 24.23cm. Forest's planting density is 6,240 shrubs per hectare, and the survival density is 3,435 shrubs per hectare. These results have far exceeded our planting goal, which was 2,700 shrubs per hectare.

生态调查说明 Forest Description

通过生态调查发现,林地中植被覆盖度达到19.21%。植被结构方面,2017-NX林地仍有较多草本层,灌木层也逐渐生长。目前在林地中共发现了10种不同的草本植物,种类有所上升,仍以沙米为主。

The ecological investigation shows that the vegetation coverage is 19.21%. In vegetation structure, herbage layer is dominant, and shrub layer is gradually growing. 10 kinds of the herbal plants are founded in the site, which is increasing compared to last year. Agriophyllum squarrosum is still the one that’s mostly found.
