Index and content
According to the evaluation index selection principle, determining the evaluation index comprises the following steps:
(1) the average water level changes, the water level is one of important indexes reflecting the management effect of the super mining area, and the water level change trend can reflect the change trend of the super mining area; the degree of change can reflect super mining district's improvement dynamics, because the exploitation groundwater deepens gradually, artifical well crowd, shallow deep mixed mining have resulted in original hydrogeological structure to take place huge change, defines the average water level from two aspects in this system: firstly, the mixed mining degree of the super mining area is serious, and the hydraulic connection between the diving water and the confined water is tight, so that the mixed mining area is defined as the mixed average water level; secondly, the mixed mining degree of the super mining area is low, and the layers are not connected, so that the mixed mining degree is defined as the water level of a mining target layer; referring to 'evaluation guide of excess mining area', the water level is divided into three categories of pore space, crack and karst water, and the average water level change index is measured by adopting an annual average value, namely the ratio of the difference value number of the current water level and the dividing initial water level to the dividing initial average water level.
(2) The area of the funnel changes, the change of the area of the funnel in the super mining area is the most direct reflection of the effect obtained by the management work of the super mining area, the enlargement of the area of the funnel indicates that the treatment effect is not ideal, and the reduction of the area indicates that the treatment of the super mining area obtains obvious effect.
(3) The well number increasing and decreasing rate and the change condition of the number of the motor-pumped wells in the ultra-mining area are important indexes in an evaluation system, and the motor-pumped wells are the most important ways for mining underground water resources, so that the number of the motor-pumped wells in the ultra-mining area can be controlled to a certain extent, the underground water resource mining amount can be effectively controlled, the well number increasing and decreasing rate refers to the ratio of the number difference between the current number of the motor-pumped wells and the number of the motor-pumped wells at the beginning of division to the number of the motor-pumped wells at the beginning of division, and the well number increasing and decreasing rate can reflect the execution strength of the treatment work of the ultra-mining area and the obtained effect.
(4) The mining volume increasing and decreasing rate refers to the ratio of the difference between the current mining volume of the super mining area and the divided initial mining volume to the divided initial mining volume, and like the increasing and decreasing rate of the number of wells, the increasing and decreasing rate of the mining volume can also reflect the execution strength of the management work of the super mining area and the obtained effect.
(5) The annual average completion rate of the substituted water source is the ratio of the annual average substituted water source amount in the area to the annual average substituted water source amount preset in the treatment plan from the beginning of division to the present.
Weight assignment
The method is characterized in that the weights of all indexes of treatment effect are assigned in an expert assignment mode, in order to embody fair science and avoid the influence of differences of experts and managers on scoring results due to research field differences, the proportion of the number of people who participate in assignment of the experts and the managers is regulated, ten people are selected according to the proportion of 1: 1, and then the given weights are averaged to obtain a final result.
Correction
The preliminary evaluation result is a result obtained by calculation according to data reported by each super-mining area, the authenticity of the result is to be lack of soil moisture, in order to enable the evaluation result to objectively and truly reflect the effect of the treatment work of the super-mining area, the treatment effect evaluation result correction is introduced in the subsection, the correction is mainly aimed at correcting the preliminary evaluation result of the treatment effect by introducing a correction factor and a calculation value, the correction is based on a water resource system balance theory in the evaluated super-mining area, and the underground water exploitable amount and the exploitation amount which are divided into the initial and current situation of the super-mining area are mainly compared, so that whether the change trend of the super-mining area is consistent with the preliminary evaluation result or not is judged macroscopically, and the preliminary evaluation result is corrected.
And the summarized data is encrypted, and the data is protected by using the collocation of the key and the key.
The main principle of the sequence cipher is that a pseudo-random sequence with excellent performance is generated by a finite state machine, and a cipher text sequence is obtained by encrypting an information stream (bit-by-bit encryption) by using the sequence, so the safety strength of the sequence cipher algorithm is completely determined by the quality of the pseudo-random sequence generated by the sequence cipher algorithm, various standards for measuring the quality of a pseudo-random sequence are provided, three conditions of a common and famous Golomb are compared, the linear complexity random walk condition of Rueppel, linear approximation, a related immune condition met by a Boolean function for generating the sequence and the like.
One of the main ways to generate a good sequence cipher is to generate a pseudo-random sequence by using a shift register, and the typical method is as follows:
a feedback shift register: the nonlinear feedback function of the order n is adopted to generate a nonlinear sequence with a large period, such as an M sequence, and the nonlinear sequence has better cryptology properties.
The linear shift register sequence and the nonlinear feedforward function are utilized to generate the feedforward sequence, and how to control the sequence phase and the nonlinear feedforward function is also a quite difficult problem.
The clock control sequence is generated by using one register sequence as a clock to control the other register sequence (or controlling the clock sequence by self), the sequence has large linear complexity, a network and other sequences are combined, a more complex network is generated by combining and applying the above methods to realize the complex sequence, and the pseudo-random sequence is generated by using methods such as a chaos theory, a cellular automaton and the like.
The main means for the attack of the sequence cipher is an algebraic method and a probability statistical method, which can achieve better effect by combining the algebraic method and the probability statistical method, and the necessary safety can be ensured only by requiring the order number of the register to be more than 100.
The advantages of the sequence cipher are small error expansion, fast speed, easy synchronization and high safety.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
