位于武夷山东南坡的闽北山区,属于亚热带丘陵山区,水热条件好,原以山青水秀,粮丰林茂而著称。但近几年水土流失问题已经到了十分严重的程度,全区十个县(市),水土流失面积达204万亩,占土地总面积的5.7％,为了摸清闽北林区水土流失情况及原因,我们以全区最大而较有代表性的建瓯县,进行调查分析,得出一些初浅的认识,仅供探讨。 一、概况 建瓯县地处闽北,建溪上游,位于北纬26°38′～27°20′;东经117°58′～118°57′之间,总土地面积达4233.13平方公里,其中耕地占8.3％,丘陵山地占81.4％,水面占3.32％;村庄、道路占7.0％。全
Located in the southeastern slope of Mount Wuyi mountainous area in northern Fujian, belong to the subtropical hilly mountains, hydrothermal conditions are good, the original Shanqingshuixiu, grain abundance is known. However, in recent years, the problem of soil and water loss has reached a very serious level. In 10 counties (cities) in the region, the area of soil erosion reached 204 mu, accounting for 5.7% of the total land area. In order to find out the causes of soil and water loss , We surveyed and analyzed the largest and most representative Jianou County in the region and came to some initial and shallow understandings for discussion only. I. Overview Jianou County is located in northern Fujian, Jianxi upstream, located between latitude 26 ° 38 ’~ 27 ° 20’; longitude 117 ° 58 ’~ 118 ° 57’, with a total land area of 4233.13 square kilometers, of which cultivated land Accounting for 8.3%, hilly mountain 81.4%, water 3.32%; villages, roads account for 7.0%. all
