阿拉善荒漠地区围栏草地建设及效益分析

CONSTRUCTION OF GRASSLAND FENCED AND ITS BENEFICIAL ANALYSIS IN ALASHAN DESERT AREA

阿拉善左旗荒漠地区自７０年代至今已兴建了封育型、培育型和种植型围栏草地（草库伦）达２６１４处，围建面积为１９０３８ｈｍ２。每年由围栏草地可收割干草１．６万ｔ，每头（只）约占有１５ｋｇ的贮备干草。封育型围栏草地的投资８８．１７～９７８．００元／ｈｍ２不等；培育型围栏草地（飞播区）每个面积均为１００ｈｍ２以上，造价相对较低；五配套畜群草库伦的面积在１ｈｍ２左右，每个平均投资２２４８～５４５２元，为２７１６～３７６９元／ｈｍ２。封育型和培育型草年产值为１６８．０８元／ｈｍ２，五配套畜群草库伦的年产值可达３２８４元／ｈｍ２。但也有近１／３的五配套畜群草库伦尚未产生效益。

reatly building grassland fenced, closing type, cultivating type and growing type, has reached 2 614 locations from 1970's to now in Alashan Left Banner desert area, and the constructing area has got to 19 038 hm2. Harvesting hay everyyear was 1.6 thousand t, and per head of animal owned storied hay 15 kg. The investment in closing type was about 88.17 to 978 yuan per hm2; and was 100 hm2 per one area in cutlivating type (aerial farming area), the price was positive low. Five complete sets of area have formed, grassland fenced was about 1 hm2, average investiment was 2 248 to 5 452 yuan per one area, and 2 716 to 3 769 yuan per hm2. Production value one year in closing type and cultivating type was 168.08 yuan per hm2, and was 3 284 yuan per hm2 in five complete sets. But there were still not any efficiency of one-third in five complete sets.
