江苏东新赣丘陵岗岭区农业资源特点与农业综合开发

江苏东新赣丘陵岗岭区，地貌形态复杂，农业生态条件优劣并存，光热资源充足，但水土流失严重，土层浅薄，有效养分贫瘠，水资源短缺，季节性干旱突出，对此必须不断建设以保水为主的工程体系，拦截地表径流，蓄积一切径流水量，增强调蓄功能，提高降水资源利用率，坚持植树造林，修筑梯田控制水土流失，实施深耕与培肥土壤技术，建立高效农田生态群落，调整农业结构，发展多种经营，明确资源优势，逐步实现规模开发与产业化过程，这

Agricultural Comprehensive Exploitation and Resources Features in Hilly Land Area of Jiangsu Province

The hilly land area in Donghai, Xinyi andGanyu county is characterized by the plentiful sunlight and suitable heat resources. Thegood agroecological condition is generally coexisted with the bad one in this area.Because of the thin layer of soil, the poor supply of soil avaiable nutrient, the serioussoil erosion, the seasonal drought, and the shortage of water resource, attention must bepaid to develop a project emphasizing the conservation of water resource. Analysis of theagricultural resources suggests that the efforts should be made to retain surface runoff,to enhance the capability of dispatching and preserving water, and to improve efficiencyof water usage. To afforest trees and to build terraced fields are also essential forcontrolling soil erosion. The technique of deep ploughing and manure accumulation shouldbe empolyed to set up a high effective agroecological system. To gradually realize alarge-scale exploitation and an industrial process, the agricultural structure should beadjusted. The resources advantage should be identified to develop a diversified economy.This is a way to develop the economy and to approach the ultimate aim of agriculturalintegrative exploitation in this hilly countryside.
