长武试验示范区高效农业生态经济系统研究
- Title:
- Study on High-efficiency Agro-ecology Economic System in Changwu Experimental Demonstration Region
- 分类号:
- S181;S157
- 摘要:
- 长武王东沟小流域试验示范区根据高原沟壑区特点，探索农村产业结构优化模式，调整农村产业结构，农村产业结构由历史上以粮食种植业为主的一元结构发展到“七五”时以种植业、副业为主的二元结构，现已变化到种植业、果业、工副业三元产业结构阶段；建立了不同降水年型粮食作物丰产抗旱技术体系，在连续干旱的气候条件下，实现旱作产量潜势的高实现率，做到粮食基本自给；完善沟坡土地资源开发技术体系，建成沟坡防蚀道路体系，提高了沟坡土地生产力，沟坡土地产值成百倍增加；实施优果工程新技术，改善果品品质，增强市场竞争力，初步建成果业产、贮、销生产链条，有力地促进了农村社会经济的发展。生态环境得到明显改善，土壤侵蚀模数稳定在800t/（km2·a）以下，林草覆盖率45%，水保治理度95%.2001年人均收入达到2523元，实现脱贫致富奔小康目标，初步建立高产高效的农业生态经济系统，探索出协调人口-资源-环境与经济发展关系问题的方法。
- Abstract:
- On the base of gully region characteristics of Loess Plateau, Changwu Wangdonggou experimental demonstration, the author explores the optimum mode of agricultural industry structure, and adjusts agricultural industry structure.The tribasic structure of planting, fruit and by product were developed from single structure in the "7th Five Years Plan" period.It has built adoption of high yield, drought resisting measures depending on annual precipitation.It is to realize potential high yield of food, and then food lives up to self support, perfects development tech system of gully slope land resource, and sets the system of erosion resisting gully slope road and enhances its productivity.To realize high quality fruit engineering advances agricultural economic development.Income per capita of local people reached to 2 523 in 2001.The eco-environment was significantly improved, such as forestry and grass cover ration is 45%, and control cover degree of soil and water conservation reached 95%, andsoil erosion module below 800 t/(kmkm2·a).It has explored a way of harmonious humans, resources and environment development.
