Influencing Factors Of Cultivated Land Use Intensity Of Rural Households In Composite Area Of Ore-agriculture

In recent years,with the development of economy and rise of non-agricultural construction land,the contradiction between the limited land resources and the growing demand for agricultural products has become increasingly prominent.Intensive utilization of cultivated land resources has become an important way for China to coordinate economic development and cultivated land protection Specifically,cultivated land utilization has influenced the sustainable development of ecology and economy in ore-agriculture zones.Coal mining brings economic benefits to local people,but also causes ecological problems,especially land destruction.Analyzing cultivated land use intensity and its influencing factors in ore-agriculture zone contributes to coordinating regional conflicts among households,arable land and coal mining,improving the land utilization ratio and promoting orderly land transfer.Based on 385 valid semi-structured interviews of households in 22 typical villages in Changhe Basin of Jincheng City,the mlogit model was adopted to quantitatively study influencing factors of land use intensity of households with different livelihood strategies.The cultivated land use intensity was calculated according to the measurement of value(including money,labor,and other factors)based on households’ scale.The Jenks method was used to classify the cultivated land use intensity into four categories:high intensive use,moderate intensive use,low intensive use,extensive use.The results of this study show that:there are great differences in cultivated land use intensity among households with different livelihood strategies.The two subcomponents of land use intensity also follow the same pattern.The regular pattern of intensive use of cultivated land for different farmers in ore-agriculture area is as follow:Ⅲ-2(human assets type household)>Ⅲ-3(ore-agriculture composite type household)>Ⅲ-1(natural assets type household)>Ⅱ(basic type household)>Ⅰ(missing type household).The constraints of cultivated land use intensity include the family land resource endowment(farmland fragmentation,farmland area per person),the situation of labor force(labor opportunity cost of farming,ownership of agricultural machinery)and land damage degree(the ratio of subsided land to arable land,the ratio of industrial and mining wasteland to arable land)due to coal mining.However,political factors(the subsidies of farmland restoration,projects that relocate people from coal mining villages)have no significant effects on cultivated land use intensity Therefore,the government should increase the land compensation for missing and basic type households because the households lack capital and technology to repair damaged land.The government should also accelerate the establishment of the land circulation market,and establish family farms owned by developing type households as the main body to improve the enthusiasm of farmers and improve arable land use intensity.
