The Farmers’ Livelihood Stratety And Land Change Interactive Research In Dry-hot Valley

In recent years, there is growing concern the relationshipbetween farmers’livelihood and land change. Human livelihoods determine the geographical environment of human activities on the mode of action. The root cause of agricultural land quality changes in our country’s ecologically fragile area is contradiction between people and land. Hot and Dry Valley has long been the unique role of human coupling, showing a similar trajectory and the different ways of land use evolution stage, Its unique system of human and land on the comprehensive research of land change provides excellent conditions. Current research relating to land a major driving force for change in focus in the "driving forces-land change" to explain the causal relationship, ignoring the impact of feedback and change the results and effects of land of farmers on the land use pattern of behavior to drive factor. Farmers livelihood is the intermediate ring between the driving factors and land use change, people respond to economic opportunities driven land use change. Therefore, Aspects of farmers livelihoods land change, ecological security, livelihood sustainability and sustainable rural development have great significance.Two typical town of Xinping County in dry valley area are research object, the investigation focused on four villages in the town, farmers in the survey data and statistical yearbook data as the data source, Analyzes the status quo of the study area each village livelihoods and land use based on SPSS and EXCEL statistical analysis; Analysis of area farmers’livelihood and land use interaction process with the way of thinking time and space conversion; Finally, Quantitative revealed changes the process and degree of farmers’livelihood and land change interaction using path analysis based on Amos.The main conclusions are as followings:(1)The analysis based on village development process showed that:Household livelihood activities to drive change in the role of the land is mainly reflected that the increased demand for household income and improve the lives of farmers resulted in the changes of agricultural land use (planting structure adjusting), as well as land use strength and efficiency;If the demand for increasing revenue and improve the lives of farmers can not be satisfied by changing agricultural land use (adjust planting structure), or land use strength and efficiency of the farmers, livelihood activities will not be limited to the farming activities in personal contract land, and out-migrantion for work, leasing land, engaging in secondary and tertiary industries, etc. may became new ways of farmers’ income.Planting structure, change of agricultural land mass directly affected people dependency level on arable land resources.Degradation of the quality of agricultural land made soil fertility decline or disappear. Farmers in pursuit of productivity gains, will have to increase investment or the use of more advanced production technology, thereby increasing the cost of production, or because of declining soil fertility, causing crop failures, resulting in reduction in planting earnings forcing farmers to re-adjust their livelihood strategies (2) Interactive analysis of changes in farmers’ livelihood strategy and land based on path analysis shows:As to the effects of livelihoods of farmers to land change, the total effect and integrated path index of employment intentions ranked in the first place, indicating that employment intentions affected land changes most significantly, and the effects paths were most widely and complex as well. The total effect of land transfer will ranked in the second place, and the integrated path index of land transfer will ranked in the third place. The total effects of human inputs and pesticide and fertilizer inputs to land change ranked in the fifth and forth place respectively, and the integrated path indexes ranked in the last place. The total effect of planting scale to land change ranked in the last place, and the integrated path index was7, indicating that the integrated effect of planting scale to land change is relatively small, and the effect path was not so complex as well.As to the effects of land change to livelihoods of farmers, both the total effect and integrated path index of land quality ranked in the first place, far greater than other land change indexes. Then, both the total effect and integrated path index of agricultural output per unit area ranked in the second place. While, the total effect of planting structure ranked in the last place, and effect path index was only one.In conclusion, The relationship between farmers livelihoods and land change influence on peasant household production and business operation behavior for mediation. Farmer livelihoods, farmers produce behavior change among the land to the farmers as the center of three interrelated, mutual restraint, either between the three changes will drive changes in the other two parties. Relations farmer livelihoods, production behavior and changes in land between arable land resources through disposal, planting techniques, production decisions, such as contact, interaction.
