| 摘 要： | 对赣江流域防护林体系的树种配置状况进行了研究。结果表明，在赣江上游的章贡区和赣县天然林面积较少，而且单位蓄积量也不高，分别只有8．06和0．38m3／hm2，而在中游的各县市中，天然林面积相对较高，在吉水、吉安和峡江县分别达到了269．8、276．0、220．0hm2；在赣江所流经的县市幼龄林面积最多，达到了2347．9hm2，中龄林次之，而成熟林的面积最小，只有57．5hm2；在各地区的防护林中，以针叶类树种为主，其中马尾松林面积最大、其次是湿地松和杉木林。

| Abstract: | Tree species disposition of the shelter forest system in Gan river valley was studied.The result showed that the area of native forest was less and stocking volume per hectare was only 8.06 and 0.38 m3/hm2 in Zhanggong and Gan counties at the upper reaches,but it reached 269.8,276.0,220.0 hm2 in Jishui,Jian and Xiajiang counties at the middle reaches.The area of the young forest in the Gan river through district was most but that of the mature forest was least,2 347.9 hm2t and 57.5 hm2,respectively.The most... |
