浅谈四川万县地区生态畜牧业的主要模式及设想

A Preliminary Discussion on the Major Models and Some Considerations of Ecological Animal Husbandry in Wanxian Prefecture of Sichuan Province

万县地区气候温和,雨量充沛,耕地少而草山草玻面积大。当前畜牧业的主要模式是“种—养结合型”、“种—养—加结合型”和自由放牧式。根据生态学原理,今后拟向“种—养—沼气结合型”、“种—养—沼气—加结合型”发展,并充分利用草山草坡资源积极发展牛羊,使各种资源得到多途径、多层次利用,化害为利,提高经济效益、生态效益和社会效益。

Nature is generous in giving Wanxian Prefecture a moderate climate, plentful rainfall, less arable land but large area of grass mountains and grass slopes. The principal models of present-day animal husbandry are 'the combination type of planting-rearing', 'the combination types of planting-rearing-adding' and athe free grazing type'. Based on the ecological principle, the future developing models should be the combination types of planting-rearing-methane, and the combination type of planting-rearing-methane-adding. Also, the resources of grass mountains and grass slopes should be fully made to develop cattle and sheep-goat production, thus rendering various resources to have the multiple-way and multiple-layer uses. In this way, making the harmful things become benefit ones canimprove economic returns, ecological and social benefits.
