Research On Agricultural Ecological Efficiency And Influencing Factors In Heilongjiang Province

As a major agricultural province in China,Heilongjiang Province,with its vast agricultural land,fertile soil and other natural resources,produces crops that are supplied to all parts of the country,and always occupies an important position in China's agricultural map.This paper takes Heilongjiang province agriculture as the research object,combs the relevant literature and constructs the evaluation system of agricultural ecological efficiency,measures the agricultural ecological efficiency and deeply excavates the restrictive factors,and finally puts forward the relevant suggestions.First of all,sort out the relevant literature,sort out the paper framework,and define the research object and related concepts.Secondly,it introduces the agricultural resources,economic development,and pollution of Heilongjiang Province,to understand the current situation of agricultural development in Heilongjiang Province.The agricultural ecological efficiency of Heilongjiang Province was measured based on the SAM model,then analyzed the influencing factors.The results show that:(1)the agricultural ecological efficiency of Heilongjiang Province is divided into two stages.The value of agricultural ecological efficiency is low from 1996 to 2011.After 2012,the ecological environment has been improved significantly,and the agricultural ecological efficiency has reached an effective state.(2)Compared with other provinces and key grain producing areas in China,Heilongjiang province's agricultural ecological efficiency ranks behind,and there is still a lot of room for progress.(3)The index of technological progress is fluctuating and rises,which contributes the most to the improvement of TFP.The improvement of agricultural ecological efficiency mainly depends on technological progress.(4)Agricultural production efficiency is the most important factor affecting agricultural ecological efficiency,followed by the level of irrigation rate.The improvement of agriculturalecological efficiency mainly depends on the improvement of productivity.Finally,according to the results of empirical analysis and the problems existing in the process of agricultural development in Heilongjiang Province,this paper puts forward improvement suggestions to promote the sustainable development of agricultural ecosystem in Heilongjiang Province...
