Study On The Trangeland Resources Optimized Pattern And Environment Capacity Of Akeqi County

Akeqi county is the most typical region that take livestock husbandry production as the main industry in the south of xinjiang. The rangeland resources is diversity and have definite produce potential. But because of the asperity of rangeland environment, the unreasonable exploitation method and Bad natural condition, the production performance of the livestock husbandry is lowly. This thesis analysis the antinomy in the production, through investigate the present rangeland resources and production condition of livestock husbandry. Under the forage-livestock coupling system and the rangeland ecosystem displacement thought, put forward the optimized utilization structure of rangeland that For the part of hungriness rangeland that improper continue to making use of adopt measure of forbid the grazing, for else rangeland that continuously making use of adopt measure of lower the utilization strength on the bases of the artificial grassland production and yard-feeding in cold season (180d). Through linear programming the model shows obvious ecological, economic and social benefit. And the quantity of sheep significant increase, the proportion increased to 64.74%, the big domestic animal quantity is about equivalent to present and the quantity of goat decreased to 27.75%, outstanding take the sheep production as the main livestock husbandry production. In planting structure the area of corn, clover , wheat and oil is 39.15%,50.58%,9.13% and 1.14%.The per capita incomes is 2572/y, increased by 143% ,compare with present condition and the livestock product raised to 20.39APU from present's 11.57APU,but at the same time rangeland utilization descended to be close to 11% . Finally estimated the environment capacity of rangeland : under optimized model the studying area can sustain the approximate and entire middle-class family life level people's population to count for 13074 and 7531 people only, for 52,47% and 30.22% of the total population at that time(after reclamation of artificial grassland). For the bad natural condition of the area we put forward the emigrant measure.
