In order to prove the global asymptotical stability of the endemic equilibrium, we introduce the change of variable which can reduce our original four-dimensional system to a three-dimensional asymptotical autonomous system with limit system.

利用复合矩阵理论以及竞争系统的Poincaré性质排除了渐近自治三维系统的极限系统周期解的存在性，进而利用极限方程理论得到了原四维系统地方病平衡点的全局稳定性。

Further more, we get the necessary and sufficient conditions for the two-dimensional discrete system, where the permanence and extinction of the system are decided and only decided by the relationship of the non-delay coefficients in the system. Further, we for the first time find the equivalent permanence and extinction between the two-dimensional discrete Lotka-Volterra and its corresponding continuous system.

进一步，本得到了此类离散系统二维自治情形下，其持续生存和灭绝分别等价于系统非时滞系数构成的相应不等式；通过比较本文中二维自治Lotka-Volterra竞争系统的连续和离散两种情形的有关结论，首次发现这两类系统具有等价的持续生存和灭绝性质，建立了这两类系统之间的联系。

Starts with the three parts of the relationship of the villages and towns government and the villager committees and the relationship of the two rural committees and the relationship of the two rural committees and villager, analyzes how the agriculture tax-and-fee reformation effects on the villagers" autonomy systematically, and think the agriculture tax-and-fee reformation will be advantageous to die down "theadministeration turn" of the village committees, meliorate the relationship of the two rural committees and the crowd, alleviate the two rural committees antinomy, promote organization construction of the two rural committees, but in the meantime also bring some series problems for the village autonomy such as public finance problem, tax fee tail owe problem etc., in the end put forward that we should push forward the villager" autonomy of the post-agriculture tax ages from the four parts of the Grass-roots Government, relationship between officials and the masses, relationship between the two rural committees and the village collective economy.

本文针对以上问题，运用理论研究与实证分析、静态分析与动态分析相结合等研究方法，从乡镇政府与村民委员会关系、村"两委"关系以及村"两委"与村民关系等三方面入手，系统地分析了农业税费改革对村民自治的影响，认为农业税费改革将有利于减弱村民委员会的"行政化"、理顺村"两委"与群众的关系、缓解村"两委"矛盾、促进村"两委"的组织建设，同时也为村民自治带来了一系列问题，如财政问题、税费尾欠问题等，最后提出应从基层政权改革、干群关系、两委关系以及农村集体经济等四个方面来推进后农业税时代的村民自治。

Finally, we get local stable manifolds and local unstable manifolds of near hyperbolic equilibrium point of nonlinear autonomous dynamical systems by the properties of bounded solutions to nonlinear nonautonomous equations.

最后运用非线性非自治中立型泛函微分方程有界解的性质，得到非线性自治动力系统在双曲平衡点的局部稳定流与局部不稳定流。
